EKGs Apple Watch and other Consumer Based EKG's

33 Upvotes

Consumer-based EKG products have proved to be valuable at gaining insight for potential arrhythmias or ruling out arrhythmia's during symptoms. This forum DOES permit consumer-based EKG's (Apple Watch, Kardia, AlivCor, etc) to be shared, but there needs to be an understanding that these devices have not been proven or validated for more advanced medical interpretation. Utilizing this data to draw larger conclusions would be irresponsible.

​

What we can read What we CANNOT (responsibly) read
Atrial Fibrillation QT Intervals
Pre-Mature Atrial Contractions Axis
Pre-Mature Ventricular Contractions Heart Failure (Ejection Fraction)
SupraVentricular Tachycardia Right or Left Bundle Branch Blocks
Ventricular Tachycardia ST Elevations
Bradycardia Q, U, J, Epsilon or any other advanced waveform

If consumer-based EKG's causes you anxiety and harm, please discontinue and seek professional help.

Artifact caused by small contact movements can cause massive distortion in the waveforms, this is not an arrhythmia.

The QALY app is not FDA approved.

Disclaimer:

Apple Watch has a Class II clearance by the FDA to detect Atrial Fibrillation: "The Atrial Fibrillation (AFib) History Feature is an over-the-counter ("OTC") software-only mobile medical application intended for users 22 years of age and over who have a diagnosis of atrial fibrillation (AFib)."

The United States Preventive Services Task Force (USPSTF) has recommended against ECG screening in asymptomatic healthy individuals due to the insufficient evidence that the benefits of this screening outweigh its harm. The concern about the potentially large numbers of false alarms that may be translated into ER visits and serve as an economic burden is another point that is brought up.

Help me , related to heart

2 Upvotes

Hello, im 25 male, 180cm and around 120kg. I take sertraline 75mg every day, and have no history of health issues, except health anxiety and slighty high cholesterol. I never smoked in my life or taken drugs and dont drink either.

Today i had some brazilian jiu jitsu training, and after the training ended, i felt a sharp localized pain right in the area where the heart is. But it was like a 3/10 and lasted for a couple seconds , so i initially ignored it. However, my health anxiety kicked in later and i went to the ER, where i am now. Did couple EKGs and they were both fine. First blood tests were done around 1:30 after onset and they showed D -dimers at 469 ng/mL , troponin T at 0,011 ng/mL and CRP at 12.32 mg/L

The doctor advised to repeat the blood tests , so they took another sample 4 hours after onset. The blood tests showed troponin T 0,020 ng/mL , and slight drop in CRP.

Then they told me to wait another 6 hours and they would repeat the blood tests.

Im 1h10 away from doing that next blood test but I am in panic, can someone give me some guidance on what this can be? I am incredibly worried that this is something dangerous that will either kill me fast or shorten my lifespan by a lot.

Interprétation ECG

Bonjour,

Je suis une F(25) et je suis très stressée à propos de ce qu’il s’est passé hier. Je suis sportive et je fais de la course à pied environ 2-3 fois par semaine. Hier lors de ma course, je suis montée à 193-195 BPM ce qui n’est pas inquiétant en soit car mon cœur monte vite lors de l’effort mais arrivé à ce stade mon cœur m’a fait ressentir 3-4 grosses extrasystoles dès que je dépassais les 190 BPM. Étant très anxieuse quand il s’agit de ma santé, j’ai pris rendez-vous chez un médecin qui m’a fait un ECG que vous trouverez en photo. Pour lui, cet ECG était normal mais il m’a dit que j’avais un QTc qui était dans la limite supérieure de la normale (460). Depuis j’ai extrêmement peur , je n’ai pas dormi cette nuit. J’ai peur de mourir d’une crise cardiaque…

Qu’en dites-vous ?

I've been diagnosed with WPW:

• Upvotes

Been having attacks since I was about 12; only got diagnosed when I was about 40.

I've got Medicaid and they keep denying me for either the pacemaker or cardioblasion(sp? Apologies), and they keep telling me I've got to be on traditional heart medications like beta blockers, blood thinners and the like, for a period of time before I'm approved.

My cardiologist has repeatedly told me to not take these, as they can adversely effect not only the secondary node, i.e. Bundle of Kent, but also the primary node.

When I go to the emergency room to stop a WPW attack, by cardioversion, I'm also severely cautioned about taking these kinds of medications.

I'm at a loss, honestly. I want to be treated but I'm being pushed and pulled by forces out of my control to, potentially, hurt myself to do so.

I have a friend 26 female and every single thing on her lipid panel was very high and her coronary artery risk is 5.88 cut off is 4.44 I think and she was not referred to cardiologist should she ask for a referral they put her on a statin but doesn’t seem to be helping her levels.

Ablation “blanking period”

1 Upvotes

Hello everyone,

I had a catheter ablation Aug 27th for SVT. I was told the ablation was successful and that I could stop taking my Diltiazem. Since then I have been having random episodes of high heart rate 100-140bpm that are very distressing. Dod anyone else experience this in their “blanking period” I have been told and have read that it is normal due to the heart “healing” but I’m really considering going back on Diltiazem so my heart can feel calm again. It’s causing me so much anxiety and I’m almost regretting getting the ablation done so soon.

Any positive feedback would really be helpful right now. Thank you 🫶🏽

Blood pressure spikes during the day, normal while lying down

6 Upvotes

Blood pressure / Epilepsy

During the day my blood pressure has spikes to 150/100 while sitting. However when I lay down in bed, it normalizes to the 120/80 range.

I am wondering if taking medication could cause my blood pressure to drop too low at night. Normally this shouldn't be an issue I'm guessing but I also have epilepsy so I'm wondering if too much of a drop might trigger a seizure.

Female, 25 years old. First, it is important to mention that my heart is structurally completely normal and that its pumping function is fully preserved.

I wanted to share my 72-hour Holter results and see if anyone here has had a similar experience.

One important bit of context is that I continued taking metoprolol (my 25 mg daily) until the day before the monitoring started, even though I had originally been advised to stop it about a week beforehand. I had some travelling and important events leading up to the Holter and was concerned about how I might feel without it, so the timing didn’t work out as planned. I realize this may have had some influence on the results.

The main findings were:

Sinus rhythm throughout the recording.

Average heart rate around 93 bpm.

My heart rate was above 100 bpm for about 43% of the entire recording.

2,275 supraventricular premature beats (SVEs/PACs) over approximately 72 hours.

Only 1 ventricular premature beat (VE/PVC).

No actual pauses in ventricular activity.

There were episodes where my heart rate suddenly increased by around 50–100 bpm and then came back down after about 3–4 minutes.

They were described as bursts of SVT.

One of these episodes was recorded when I changed position.

The overall conclusion still states sinus rhythm, and I’m being followed up by the arrhythmia clinic.

For context, I’ve been experiencing very noticeable changes in heart rate with posture, especially when standing, along with dizziness and only one time presyncope, sometimes cold hands while upright, and episodes of tachycardia. POTS and IST have both crossed my mind, although I obviously don’t know yet what is actually causing this.

Has anyone had similar Holter results? Did POTS or IST eventually turn out to be part of the explanation?

I’m also curious about so many PACs/SVEs — if you’ve had a similar amount, did you ever find out what was causing them?

EKGs Abnormal EKG at ER

Post image
1 Upvotes

I live with EDS, chronic iron deficiency, and have heart palpitations. I have gone to the ER a few times over the last few years for higher heart rate, and was always told it was fine, I was fine.

I got very sick the other day, felt weak and had terrible heart palpitations, so I went to the ER.

They told me that I had an abnormal EKG, and that it was also abnormal in 2025, but *no one ever told me it was abnormal in 2025.*

I’m going to do an echocardiogram, holter, but I’m scared shitless. My doc initially felt that some of these things could be attributed to low iron stores, but it seems like some of them are a little beyond iron’s pay grade.

I don’t even know what I’m looking for. I feel so sad, very betrayed and wished I was told about this last year when I could have responded to it and done something about it then.

should I be worried?

Has anyone experienced a deep burning, adrenaline-like sensation in their chest immediately after waking?

2 Upvotes

I’m 29 year old female.

I've been experiencing a strange sensation in the left side of my chest, almost like a hot chemical or adrenaline rush spreading through my heart/chest, almost like a burning sensation on the left side.
(not sure if burning is the right word, but it’s hard to describe). I don’t think it’s reflux as I’ve had reflux before and it doesn’t feel like that.

It usually happens in the early hours of the morning, sometimes literally a second after my alarm wakes me up or sometimes it wakes me up on its own. It slowly builds, lasts around 1-2minutes max, then gradually disappears. Afterwards I feel completely normal, just really awake. (Apparently it’s too short to be angina?? But it feels like it could be?)

I've noticed it's worse after stressful days, caffeine, alcohol or stimulants, and much less frequent when I'm relaxed or on holiday.

I am a healthy weight and eat healthy, although the last year or so I have not been exercising as frequently as I used to (I struggle to get to the gym tbh) I also probably don’t manage stress that well so I seem to be in fight or flight mode lately.

I had mild pericarditis following a Pfizer vaccination several years ago and took around six months to recover. I've recently seen a cardiologist about these newer symptoms, and she said my heart looked healthy and recommended exercise and avoiding stimulants. (I was a bit disappointed that she didn’t do further tests, and left feeling unsure)

I'm wondering whether this could be an autonomic nervous system response, adrenaline surge or something like coronary artery spasm.
Has anyone experienced anything similar, particularly immediately after waking? Did you ever find out what caused it?

I have been advised to have pacemaker installed to cure my slow heart rate (40-45 bpm) & low blood pressure. I can’t afford private hospitals cost, neither I can travel to my home country due to serious health issues. Can someone advise where should I approach? Who is the specialist cardio Electrophysiologist here in Sharjah Dubai or Ajman, what is the cost in Govt Hospitals?

Mild Aortic Insufficiency, no BAV

1 Upvotes

25M, no family history of heart disease. Referred to cardiology for echo because of EKG right axis deviation of 93 degrees which turned out to be a normal variant in fit individuals.

First echocardiogram was done by a doc in training. They took a bad picture but used it to diagnose me with BAV and mild aortic insufficiency. Second echocardiogram one week later was done by a different doctor and they said my valve is actually tricuspid. They still wrote down “mild aortic insufficiency” on the report.

All measurements are normal. EF was 60-65%. Stress test was 19.3 Mets. PHT values were 599ms on first echo and 540ms on second.

Is it likely that they also misdiagnosed the mild AI? How common is this in people my age? I get really anxious reading the reports, even the one with the misdiagnosis.

Annus Horribilis

Last year, I was completely blindsided by multiple cardiac diagnoses. CAD, heart failure and ventricular tachycardia. I saw more doctors in the past year than I had in my entire life previously. I've always lived a healthy lifestyle...never smoked, decent diet, regular exercise. At 74 I have a body builders physique with a 32 inch waist. Needless to say, I was shocked and a bad heart was never on my bingo card. After a battery of diagnostic tests it was found my ejection fraction was only a tiny bit below normal...here's a pill. My arteries were only slightly obstructed...here's a pill. Two cardiac catheterizations later...no, you don't need stents or bypass surgery and no, you don't actually have v tach...here's a pill. Good news all around I suppose but now comes the task of rebuilding my sanity and self confidence overcoming the notion that I was a ticking time bomb. Is the mental trauma common?

Hi. I’m 34, a mom of two little girls. It’s just over a year now that I have developed tachycardia, lots of heart palpitations. Dizziness from time to time, shortness of breath especially with exertion. 6 months ago I also developed chronic headaches. Been to cardiologist, gastroenterologist, ER 3 times.. and so on. I also have intermittent pain in my left breast that radiates into my shoulder and arm. I’ve also had 2 ultrasounds of my breast and a mammogram. MRI of my thorax. And nothing…. It’s so difficult dealing with this. I’d like to know if anyone experienced something similar.

Im a 22 yr old male, I has a EKG done today because my heart was racing and I felt a bit dizzy. Im prescribed vyvanse and it causes my resting heart rate to be 90-130 throughout the day. I’ve had all types of blood work and labs done recently and they’re all perfect. Also had a recent echocardiogram and holter monitor test and they were all clear. They thought my EKG today wasn’t alarming but looking for some more opinions. The machine suspected ACS so it kinda worried me.

Second Opinion Early stage hipokinetic cardiomiopaty.Please read my story so you can understand 🙏🏼

2 Upvotes

hey guys, Please give me an advice.

promise i wont come with same question again.

I am a 31YO female

In 2017 (First cardiology visit) Found T inversions v1-3 and Mild apical trabeculations at the apex. Had stress test and echo and all fine. EF was 55-60% doctor was not concerned.

2024 - Had MRI and Holter for the Pvc that I had just in bed before sleeping ( Anxiety started as My dad passed away at 65 sudden in sleep, but with symptoms of Heart attack) No early death or sudden in my family. Doctor understood that they suspected me in My country for non compaction but no, they suspected me for Myocardial bridge. So they asked for MRI for a suspection of Non compaction cardiomiophaty

MRI showed mild reduced EF 56% (hipokinesia)

no fibrosis ,scar, or other abnormalities but Said that im suspected or Early stage hipokinetic non dilatated cardiomiopaty and plan was to repeat the Echo 3 years later . I said Okaaaay and didn’t care

in 2025 I started with bad panic attacks, somatic Anxiety, sometimes , HR is up every morning for the first 30mins(90-110) And I feel heavy, Scared, chest pain ( few seconds) even hand pain😅

CT is perfect so no ischemia.

I ve been so many times to AE (38+ in 1 Year) with Anxiety attacks and also I must confess.. I did lie few times about pains duration, That I get breathless while walking and so on.. because I been so many times and I couldn’t tell them: You know.. I had doom feeling and some heat around the body)

And now every cardiologist in UK is looking at that “suspected cardiomiopaty”)

my EF at Every echo is 60% and I had 4

Stress test show no hypokinetic or reduced EF . Is (60+)

or cardiomiopathy usually sits quiet ?

I wonder did I made the doctors add and continue with this diagnosis because What I told them ? I am even scared to belive doctors anymore because:

I had CT in Uk and showed possible LAD stenosis 50-70% LAD. And started statin and aspirin 3 months

Treadmill was negative for ischemia and they discharged me and booked a stress Mri (with adenosine)

because MRI was not ready after 2 months and I was so scared for my life that, I did call hospital so

many times told them : Hey I got Lad stenosis And I need MRI to see if I must proceed with angiography

The result was All fine Viable segments ,Heart function 60%+ (but keep in mind it was stress mri) but possible Ischemia in 2 segments within Lad

doctors added me to waiting list for invasive angiography.

So I did Fly to my country , And had repeated CT on a very performant CT scanner(Somatom Force)

and showed 0 calcium and 0 stenosis(perfect CT)

They didnt want to listen to me that I have a perfect CT in Romania and they said that because MRI they cant listen to Romania CT

I did book privately with my Cardiologisst and gave the CD with my CT angiogram and so, Doctors and tehnicians compared the CT and they sent a letter saying that ( Stop statin and aspirin) There were artefact in processing images

that s why I am scared .. what if they tell me about cardiomiopaty because I already had a “suspicion” which is not true.. I explained the doctor wrong As they suspected a myocardial bridge as per Ekg

I repeated Echo 3 weeks ago and was ok… 60% amd no hipokinesi

Is better to search other doctors in my country for the MRI ? To accept I have early stage cardiomyopathy for the past 10 years and no medication ?

i had repeated mri here but by the same doctors. results are not ready yet

Necessity of nuclear stress test?

1 Upvotes

Hello, I (early forties) am trying to get more information on a scheduled nuclear stress test.

Recently I was running on the treadmill at an incline and my watch said my HR was too high. I started having left-sided chest pain, not crushing but sharp. I did a cool down and the pain alleviated somewhat, but it still stayed for about an hour at rest.

Another day I got on the treadmill with no incline and at a lower speed. About 15 minutes walking, I felt a similar pain that lasted not quite as long. I didn't have shortness of breath, sweating, or any pain in jaw or arm beyond usual pains.

I saw my PCP two weeks later, who referred me to a cardiologist I had seen a few years prior (had stress test, Holter, and echo for PVCs, all clear). I also had a procedure that was canceled for cardiac clearance before I could see the cardiologist.

My cardiologist wants me to get a nuclear stress test versus a regular one. I believe this will still be a treadmill test, but with the isotope imaging. Looking at the radiation levels, I have concerns. I've had multiple CT scans this year, and it feels like a large hit all together.

Is there a clinical reason to get the nuclear stress test versus the regular kind? Is the reasoning because of the chest wall pain, given that my previous imaging was normal? Is it necessary for cardiac clearance? Would it be too forward to ask these questions on MyChart?

I'm trusting my doctors, and I do have family history (stents in first-degree relative at early age). I just am hesitant about a nuclear stress test given my age, no major risk factors like smoking beyond family history, and the balance of risk with the radiation and the likely outcome of it being rib pain.

Any thoughts are appreciated. Thank you for reading.

Diagnosed with wenkebach after PEME

1 Upvotes

Hi everyone! I recently found out that I have Wenckebach heart block (Mobitz Type I), and my resting heart rate was 43 BPM. I was advised to follow up with a primary care physician for further evaluation.
I recently completed my pre-employment medical examination (PEME) for a cruise line, where I’ll be working as a dancer. Unfortunately, my medical status is currently listed as “temporarily unfit” until I receive further medical clearance.
For some background, I’m 25 years old and have been dancing since I was 5. I’ve competed in dance for many years and participated in high-endurance sports, including track and field, when I was younger. I’ve always been physically active and have never experienced any heart-related issues, dizziness, chest pain, or difficulty performing intense physical activities.
This diagnosis honestly caught me off guard because I’ve always considered myself healthy and physically fit. I’m also worried about whether this could affect my chances of getting cleared for the job.
I’ve worked incredibly hard for this opportunity, and becoming a dancer on a cruise ship is something I’ve really been looking forward to. I’m scared that something like this could prevent me from pursuing my dream.
Has anyone experienced something similar, especially athletes or dancers with Wenckebach heart block and a low resting heart rate? Were you eventually cleared to return to physical activity or work?
Should I be concerned, or is this something that can be considered normal in highly active individuals?
I’d really appreciate hearing about your experiences. Thank you!
