Q. What do you mean by Ventricular Arrhythmias?

Considerable disagreement exists regarding the significance of resting ventricular ectopic beats. In study comparing the coronary angiogram of patients exhibiting premature contractions to those who did not, it was found that the degree of coronary disease was severe in those with the arrhythmia. When exercise produces an increase in the number of arrhythmias the incidence of mortality is increased. Frequent multiform PVCs constitute a risk in those with poor ventricular function.
