Hi, I’ve just started using the X2 and on a 40 minute activity there’s just under 2% Other Rhythm (split over 3 markers). On each marker the ECG shows one beat with either an elongation or slight irregularity. For those that have more experience with the X2, is there a degree of error/noise with the ECG (especially when moving around) that may register as ‘Other Rhythm’ markers? Thanks
