Each time, I stopped running, and they would go away once my heartrate slowed. The onset was abrupt. I used
to run 3-4 times per week 3-4.5 miles at a time, and was in great shape. I've had this checked out with an echo, stress echo and holter, although this never happened while I was hooked up--only rare (2-4) PVCs during monitoring. No structural heart problems, other than slight MVP and most recently, mild aortic regurg.
