Can you actually visualize the heart rhythm using a Polar band? For some reason, I always thought they only sent the pulse rate. Or are you able to detect AFib

  It’s what a doctor does (at patients bedside, without ecg) - irregularly irregular; fast or slow, high degree of accuracy

  Newish Polar bands (H10, maybe H7) send data on each beat. There are apps that use this to track heart rate variability (the variance in the gap between heart beats) which can be used as a measure of "readiness" in athletes

  Yes, it is clearly obvious just from pulse rate when my heart goes out of rhythm.The rate suddenly spikes and becomes highly variable. It's just as obvious when it drops back into rhythm. For me, that's typically a few minutes or hours after it goes out.
