Q. What do you mean by  ST-Segment in Exercise Induced  PVC?

Ans.

Over the years it has been believed that repolarization in ventricular ectopic beats had no diagnostic significance. Recently the magnitude of ST depression in ventricular ectopic beats near peak exercise was studied and was found to be of significant diagnostic value. Because most patients do not have PVCs during exercise, testing limits its value somewhat; ST depression greater than 10 per cent of the R-wave amplitude is predictive of an ischaemia response.
