@lenmayo I have one and take my ecg daily. Never been out of sinus yet.

@lenmayo curious as to your experience with Kardia vs Smartwatches. I will share mine. I had ablation for Aflutter in 2017. Next year I purchased 1st Kardia mobile- 2 fingers on this 1 x 3 in sensor. Got some good traces but sinus rhythm so not so much use. I carried it in my wallet. A few months later it was dead, replaced the battery with no success. So I purchased another and used it for a while before it too died so igave up and purchased a Samsung smartwatch to go with my Samsung phone. Very similar traces and diagnosis to Kardia but easier to carry around. In 21-24 I started experiencing a lot of ectopic beats- mostly PAC. Also had a few short spells of AF. Annoying thing is that the Galaxy watch would diagnose the ectopic traces as AF which my EP as well as QALY disputed. This made sense as the ectopic episodes did not increase heart rate as I experienced with AF attacks. I kept reading that Apple Smartwatch was best at deciphering AF from recorded traces sooo… I went through the agony of changing from Samsung to Apple Iwatch 10 in jan 2025. Pretty much the same experiences as Kardia and Galaxy- good at detecting Sinus Rhythm and pure AF but misdiagnosis for the traces with PVC/PACs in them. All three devices produce nice traces equivalent to 2 lead ECG so you can capture 30 sec traces anytime aWatches are a little more convenient plus I havent had any die on me. I even purchased another Kardia sensor that is like a credit card and fits in
My wallet without being damaged but the traces aren’t any better than from the watches. The Kardia sensor is less costly than smartwatch but one can buy refurbished watches for fairly low price on EBay or Amazon.
