I'm just curious, is this normal? Tonight, I warmed up for only 4 or 5 min before jogging. My bpm was 66 and in 4 min, it was 186. I stopped, felt my pulse - it was very fast but I wasn't even breathing hard. It pretty much dropped back to 119 immediately so I started jogging again. I have my monitor set to beep at 185. Went down a hill and 1/2 way back up the other side & it started beeping again, up to 192. This has been 8 minutes. I stopped and it dropped slowly to 160. Started jogging again, back downhill & hit 195 but I just kept going. It bounced up and down, 190 to 120 and then it'd maintain in the high 180's, low 190's & then bounce again. After 2 miles, I sprinted for 1 block and hit 222 for a few seconds. When I stopped, it dropped back to the 170's and then I walked for about a block and it quickly dropped back to the 80's. Most of the time I jog, I can maintain 120 to 150 - if I have the dog, it's even lower cause he stops so much. But, about every 4th or 5th day of jogging, what happened tonight occurs. Of course, this didn't happen when I wore the 48 hour monitor.
