Samsung Watch EKG Feature

My cardiologist tells me that there is too much artifact on the ECGs done with the Samsung watch and app. Any suggestions? Has anyone else had that problem? The app reads whether or not I am in a-fib but the cardiologist would like a cleaner tracing.

Hi @iowafemale. I understand your interest in having cleaner tracing with your device. I found this earlier discussion on Samsung wearable devices so you will notice I have moved your question here to continue to explore the capabilities of your device with help from @johnbishop who is quite tech savvy.

In the meantime, I wanted to share the following article on "How useful is the smartwatch ECG?": https://www.sciencedirect.com/science/article/pii/S1050173819301495

One thing to note is that wearable devices are typically only an indicator of possible issues and would recommend always to follow up with a doctor if you have questions on a reading.

Given that your cardiologist has concerns, what were his/her recommendations with regard to the watch and app?

Thanks for the mention @amandajro.
Hi @iowafemale, I have one of the older Series 2 Apple iWatch's and I bought one of the Kardia ECG pads when they first came out. After I had it a few months and had been taking an ECG along with my blood pressure every morning. I have hypertension and do take blood pressure medication but had really never been concerned with Afib or arrhythmias until one morning on a weekend the app popped up with an possible Afib reading. I had some anxiety and called my healthcare insurer who have a nurse hotline for questions. She told me to have someone take me to the emergency room. Being a guy and feeling OK, I decided to wait and took the ECG a couple of more times. The Afib reading went away but it showed "unclassified" reading so I didn't go in and decided to mention it to my Mayo doctor at my next appointment a few weeks away. I gave him my phone and he talked with a cardiologist and mentioned it looks more like PVCs and thought it wasn't something to worry about. They both agreed it wasn't Afib so that made me feel a lot better but a little questioning about my Apple watch and the Kardia device.

Then I started thinking about my different health conditions and one being peripheral neuropathy. I use my fingers on the pads for the ECG and the thumb on the Kardia watch band I also have and both rely on the nerves (I think) in my fingers which are probably not that great. I think your Samsung watch with the ECG may have cleaner readings than my older iWatch but I still think they both will only be a possible indicator and the doctor/cardiologist is the one that can do the interpretation if a regular ECG is needed. Possibly it all boils down to one lead into the electronics for recording?…but that's just an uneducated guess 🙂 My Apple watch has been showing me Afib readings for a couple of years now but they are interspersed with normal and unclassified readings. I've been thinking of getting a new Series 4 Apple watch which probably is similar to the Samsung in how they work, not needing the small pad for the fingers.
