@heartache The Kardia 6L is a pretty nifty device for the price, but it is a poor substitute for a proper 6 lead ECG and it isn't a 12 lead, which the cardio/EP team would want in order to get a definitive diagnosis. The EP I went to did my index ablation, but I was in the ICU six whole days later and shortly put on amiodarone because my heart was in a nasty chaotic arrhythmia. I went through the ten week blanking period, where the heart calms and all the multiple lesions heal up to scar tissue, and then comes the Holter monitor worn for about a day or less. In my case, my Holter showed a lot of PACs, not a good sign. About six weeks later, I broke into AF again, but this time I made my Samsung Galaxy watch take an ECG. I uploaded the file to my PC from my phone's controlling health app, and sent it to his nurse. He immediately accepted the Galaxy's assessment and agreed I had recurrent AF, and scheduled me for an ablation three months later. So, while the wearables are by no means foolproof, or even very reliably accurate, they can indicate a potential problem and the conscientious EP or cardiologist should invite you in for a proper 12 lead assessment. In my case, he didn't want to see me....he believed my watch's depiction which was my typical chaotic rhythm, no obvious P-waves before each QRS, and the peak-to-peaks were very obviously variable. He could hardly argue. 😀
