in the last weeks, sometimes when I am training (running intervals), during my jog between intervals, my
pulse meter starts to show a very high
pulse. My max
pulse is about 170, but during these periods it may register over 200 for 1-2 minutes.I have written this off as a problem with my pulse meter.This has happened about 4-5 times in the last month. Can it be that my heart is actually beating this fast or must it be a technical problem with my watch.
