Q. Describe Induced Ventricular Arrhythmias?
The prognostic significance of ventricular ectopy provoked by stress testing after an MI is controversial. Complex ventricular arrhythmias detected by ambulatory ECG monitoring during the late hospital phase of an infarction have been reported to adversely affect prognosis. The reported incidence of post MI exercise induced ventricular arrhythmias range from 20 per cent to 60 per cent.
