ECG / EKG test surprise you? Did it alert you on issue?

[Julien]

Just for kicks I decided to recored my ECG right after cardio today. Weight trained (shoulders)>20 minutes Stair Stepper>25 minutes Elliptical>Treadmill 1 mile at 7.5mph/8 minute mile.

As soon as I got off the treadmill I did an ECG and said HR was high. Then did 3 more and got inconclusive and thought is was discarding or not saving this data so I keep trying. On the 4th ECG my HR had dropped below 100BPM and got a Sinus reading. On my HR Recovery you can see when I was running the ECG. Also see another ‘blip’ misread on my highest HR at 8 seconds.

My ECG looks very strange after I did a 2-mile run. It's barely readable.

You must have allowed for recovery since your HR is only 116BPM. Also looks very 'flat'. Does it look more normal at a resting state and do you Sinus?

Next time I will wait for recovery yeah I measured right away after threadmill run maybe that's why it looks so out of place.

No, I was asking because your HR is ONLY 116BPM. That is near recovered and just above normal standing/walking. You only need to be at or below 100BPM to get a conclusive ECG. Are you running and do you know your perceived exertion. Unless you are >70 old then 116BPM should only be about a 3 on the perceived exertion scale. I was at about 6 to 7 perceived exertion when I did my first reading. Also all my readings look about the same with the exception of number of samples (BPM). Even the first one when I got the High Heart Rate warning.

This is a very interesting thread, unfortunately just another thing for me to obsess on, I have already taken 28 ECG All Sinus rhythm which is cool because I do have skips (I was told it doesn't skip but just early ectopic beats) but only when I'm under stress or anxiety, and my heart rate is never high or races unless I do cardio, and then it never skips oddly enough.

I have found out as you all have, when under stress or after workout these readings can look very odd, when I was under stress I took one and my T-waves were very tall, worried and thought I had hyperkalemia (too much potassium) I read that doing a crash course on ECG readings (dangerous), but in that case T-waves would be more tented like pinched at the top. Anyway, I'm going to get a full ECG in the new year, for now this is interesting, and seems I don't have a-fib, as much as try or worry about it.

I think my ECG is maybe OK?? I think my R wave should be higher, T wave a little smaller and P wave a little higher, and maybe I have a slight ST elevation, but these readings are far from perfect with plenty of artifacts, People say I'm a hypochondriac I don't think so...

I totally agree with those other people. 28 ECGs you say?

Still updating, but for those who did and tested, anything interesting on your ECG?

Not for me. Mine was pretty normal. What is surprising, my Mom has a valve issue on her heart and hers isn't picking it up. A regular EKG does though.

I had periodic heart palpitations starting a few years back. Never had any idea what brought them about. About 2-3 days before the ECG release I had another one - which since I had my Watch 4 at the time - I ran the heart rate app. HR went from 68 to 170 nearly instantly, and after a short while dropped from 170 to 68 instantly as if nothing happened. My HR wasn't actually 170, but just irregular.

They happen very infrequently, and when they do, they are in clusters. When puzzling over the timing - months without them, then several over a short period, followed by none for a long time again, I noticed that they coincide with my seasonal allergies that started up in my late 40's. Specifically the times I take allergy medicine with pseudoephedrine. Looked it up, and yes, this is a side-effect. I'm not willing at the moment to take some for the hell of it to see if it will happen again. Since the ECG was installed, I have it set to monitor and check manually myself frequently. Nary a peep from the watch, all readings are what it calls normal.

Something to mention during my next checkup.

A valve issue picked up by EKG? That's an inaccurate description of what an EKG can detect.

It is rather disappointing.
It doesn't even work with my dry fingertip. I have to put some saliva on it to make it work.
Even the Slightest movement of the crown will make it confused.
As far as I am concerned, this ECG is a gimmick and not a real device for medical use.

Haven’t had an issue with my dry finger but I put lotion on a few times a day. The slightest movements from traditional leads pick up the same noise. You might think it is a gimmick but the people who have had it show an issue and have been treated might disagree.

You need a good electrical connection, a little salty water for instance.

I have only a momentary issue with the reading at first. After about 4 seconds it is stable reading the remainder of test.

 

[MadeTheSwitch]

Nope. No surprises. Well maybe a surprise that I am still okay, alive and kicking after having had problems before. Which is the whole reason I got a watch in the first place. So far so good though.

WOW! I LOVE this thing! It says I'm till alive this morning!!! What confidence I can exude now!

My AW4 finally paid off!!

This weekend my AW4 finally recorded what I was feeling on very rare occasion for decades.
I saw a few doctors and specialist, but they reported normal pattern.
Because once I saw the doc, the issue was long gone.

Well, I was felling a PVC occur, a premature ventricular contraction.
A nearly harmless "short circuit" of the heart beat.
This image is close to how my pattern looked.

I never felt dizzy, only had a light cough after (felt like a tickle or light poking).
Far more uncomfortable/annoying than dangerous, IF you even notice it.

Yes, it is a relief to finally know what was happening. Concerned, not frightened (and at least know doc says my heart is in generally good shape).

Doctor (has AW3) read up data on the AW4, says AW4 is not as good as clinic grade (of course!), but obviously does help in recording on-spot issues long before getting to a clinic.
Naturally Apple is pushing not to rely on AW4 for diagnosis.

Doc was quite fascinated about the AW4 and enjoyed me showing her how it works. She said she was planning to get one herself, but I think soon will get upgrade.

Because once I saw the doc, the issue was gone! The events lasted up to 10 seconds, so I needed a device on all time time (over a Alivecor® KardiaMobile or something similar)

Glad you got it figured out. Like you said, PVCs are not usually dangerous unless you have a crazy number of them...but sometimes just knowing you are okay is a wonderful feeling and relieves stress! I know the watch can’t diagnose them so did you send the ecg to your doc?

She could not receive them, I guess clinic policy.
She said looking at it was sufficient.

For sure, I was worried and annoyed before.
Now I am just annoyed.

Every once in a great while, I would feel an irregular heart beat. I consider myself healthy and go to the gym all the time. I caught an irregular heart rhythm when resting one day but I’m not at all concerned.

My regular workouts (mostly weight training) which I usually do 5 days a week. My HR fluctuates a lot during these workouts due to sets/reps.

Those are PACs, premature atrial contraction. Completely harmless.

Have you been diagnosed with anything. You are the first person I’ve found that has their Apple Watch ecg look just like mine when I’m in sinus. The r wave goes up just a little then drops down a wave but goes below the base line. To come back up. I see lots of people with the tall thin r S wave. So have you been diagnosed with anything at all?

 

[Julien]

No

I keep getting flutters/palpitations but have not had anything show on ECGs at the doctors. Does anyone think it’s worth another visit based on this? Thanks

You show them this?
Docs have a 24 hour recording device, with 12 points (not 1 like watch). Ask about that.

Yes, I have shown previous recordings to Docs. They don’t seem concerned. I will ask again about the 24 hour recording device. Thanks
