taken ECG on my Apple Watch and it’s gone back inconclusive 3 times now Feeling a little jittery What can be the cause of no reading

Did you feel jittery before you tried to get an ECG from your Apple Watch? I've also gone on how I feel.

[babs1234 in reply to Thomas45]

Yes. That’s why I took it

From my experience, its most likely poor contact or movement or moist under watch, maybe even electrical disturbance... something nearby that can affect it?

Best way is be relaxed with arm resting on desk or armchair and just gentle contact from finger wait a minute or two before you start... also if you press too hard the watch can move. Hopefully your just anxious like me and its nothing. I find i don't do ECG now unless watch alerts me, i'm far more relaxed!

I get inconclusive readings on my Apple Watch for my LBBB sometimes. Inconclusive just means it senses a rhythm that it doesn’t recognise. Watches only recognise AF or sinus. It will also detect high or low heart rates but anything outside of that is ‘inconclusive’.

Hi Apple Watch will only ever say ‘possible AF’, inconclusive (you were jittery, poor contact between watch, skin, finger, or if heart rate is less than 50bpm it will also say inconclusive. If over 50bpm and no af it will say ‘sinus rhythm and does not display signs of AF’.

Because I have low heart rate bradycardia, I run all my ECG through an app called Qaly that analyses them for 20 different arrhythmias.

It is a paid app but I find it excellent and very reassuring and my cardiologist has been very impressed with it.

Hope this helps.

Best wishes

My watch has told me inconclusive many times. I had Aflutter before it went to full blown Afib and I wonder if Aflutter is not registered by the watch. I also have a pacemaker and the inconclusive usually disappears after several minutes for me.

Yep I think the watch is probably detecting a lot of noise / flutter and possibly different arrhythmias and hence saying inconclusive.

The app Qaly will be able to analyse the ecg for you and will (example) say 3 x pac, 1 x pvc, bigeminy etc all detected within one ecg.

If the AI can’t analyse the ecg (rare but happens occasionally) then it is handed off to a human technician.
