I thought an apple watch identify afib history too.

You have to know if you have afib though, which can be tough to detect for people with infrequent and self limiting cases.

Example; I get bigeminy PACs, which apple watch flags as possible afib when there is noise that obscures the p-wave. But my cardiologist has seen the pattern on a more sensitive device and says it’s not afib.

Also one can have arrhythmia that is not afib
