Anyone had any experience of using either Heart Tec or Vista Health for a 7 day ECG. I had a 12 lead ECG at hospital which showed a low p wave but nothing to worry about last year. However they have got much more noticeable and my smart watch shows atrial fibrillation briefly most days (will show for one reading and not the next one seconds apart). There's a 12 month wait in my area to see a cardiologist so was wondering about arranging a 7 day ECG but not sure if I'm wasting money.
