Question I work out about 4 days a week. One day about two weeks ago I was running on the treadmill until my heart rate was 154, then started to slow it down, walking at a fast but steady pace, when all of a sudden, my heart rate dropped from 140 to 120 in mere seconds. I just watched the numbers plummet. That sent me into an anxiety attack ( I think) where a wave of vibration went through me and my legs got all jittery.
Since then I have been taking it easier and not working out so hard, just walking at a 3.0 m/h pace. Just yesterday, I noticed that my heart rate kept going up and down from 116 down (one point a second) to 108. Then back up to 117 or 120, then back down, and so forth. My walking was steady with no increases or decreases in effort.
Before the treadmill I did the eliptical with a pretty steady rate of 130 but by the time I walked over to the treadmill and punched in my program, my rate was 78.
I felt no dizziness or lightheadedness. No symptoms whatsoever except fright for what could be wrong with me.
I am 39 years old. I am on levothyroxine and Asmanex for my thyroid and asthma.
What could be wrong with me?
Answer Dear Tracy
Nothing is wrong with you in my opinion. It's okay for heart rate to jump around so long as it doesn't exceed 145. Please continue to exercise as much as you want.
