Polar monitor or PM malfunction?
I recently rejoined the gym and have been experiencing odd readings on my Polar monitor. It will jump to above my high rate then show a reading of anywhere from 0 to 140 then level off. It primarily happens when doing isometric exercises for core strengthening as opposed to on cardio equipment. I wore it outside the gym to rule out interference from equipment and it happens when at rest also, although not as frequently. Since I'm not sensitive to fluctuations in my heart rate, I can't really tell if it is a malfuntion of the polar monitor or that the pacemaker settings need to be tweaked. The polar monitor isn't very old and they are supposed to be very accurate. I am 100% paced with a dual lead device. Has anyone had similar experiences or have any thoughts?
