I'm 44 5'6 tall 168lbs , had a stent implant at 40, been training for a marathon, done quite a few halfs. recently on a 17 mile run i noticed my heart rate drop from the jogging 140BPM right down to 90 for 15-30 seconds, then back up to 140 avg, this happened twice in my run. I use a garmin, top of the range, never seen this before. should i be concerned ?thanks





Thanks Lisa, I need to wait a week normally for an appointment and had a 20 miler scheduled for Saturday, i phoned like you said, his opinion was if there was no other systems (outside my panic :-)) then its was likely the gamin playing up. I've seen the indication disappear once or twice but to drop to a number seemed odd, did my 20 and still here. Thanks for the note
