I was out cycling today and noticed a pounding sensation in my chest that I get every so often (maybe 3-4 times a year and feels like an arrhythmia) - generally when I'm cycling, but not always. I switched over to my HRM (heart rate monitor) readout and watched as my HR jumped from 155 bpm to about 211. The increments jumped by 10's and 20's, over the course of about 15 seconds, so it could have gotten higher before the readout indicated my HR had leveled\maxed out at 211. I did what I usually do when this happens - hard coughs (this is supposed to help the heart get back into a regular rhythm) and took very deep breaths while I slowed my cadence. I've spoken to another cycling buddy of mine who says his heart does the same, periodically. Have any of you noticed this when cycling? It took about 2 minutes for my HR to drop down to about 145 bpm and I was fine for the remainder of the ride (about another 20 miles on a 50 miler).
I have a yearly physical and, from what I've been told, I'm in great shape. My pulse is currently down to 56 bpm and I had an EKG, by a heart specialist, about 3 years ago. She said I was right as rain. I'm 45 and my recommended max MR is 175. The 155 did seem unusually high (it's normally about 122-132 when I'm cycling) but I've recently increased my cadence and brought my average speed up by about 1 mph, over the last 3 weeks, so I wasn't surprised to see an increased, sustained HR, although it's usually 145 or so since I stepped things up..
On a side note: Many people have told me they don't rely on their HRM to give them an accurate reading. Keep in mind, I wasn't watching my HR readout initially. It was only when I felt a noticeable rhythm change that I switched over to my HRM. So it was definitely a "real event."
