Ofcourse, the incidence of PVC s can not be taken lightly. We say they are the precursors for major cardiac arrhythmia
. A person may have (or may not) little chances of ventricular fibrillation
which is dangerous.
There is some thing called as benign variety also in PVCs. I suggest you to consult a cardiologist
, considering your age. Some sort of anti arrhythmic therapy would be required.
