Heart rate slows suddenly while sitting

[wooded2001acres]

When I sit up my pulse rate falls below 40 into the 30's. When I lay down it goes back up to above 50. Do you have a similar problem?

When I use my elliptical it does. I will do a warm up and stretch and start out slowly, but when I try to do 30 second quick intervals, my heart rate will go from the 130’s down to the 90’s. Then as soon as I slow back down it shoots up into the 180’s. It will take up to 3 minutes to get it back to a normal cardio. It’s like my heart is doing the opposite of what I need it to do. (I have had two ablations for SVT and am scheduled for my third next month.) But my electrophysiologist doesn’t seem worried about it. It sure worries me!

Have you had any issues in the past?
