i was at the health check/mot few years ago and the ecg showed a couple of irregular beats. cardiologist asked few questions if i notice or feel any effects, i said not at all. he said many people have mild arrhythmia, and it only requires attention if irregular beats exceed a certain amount per day (10,000 in 24hrs, iirc). perhaps a more in-depth assessment would be interesting, but i only want to hear positive results, haha!
