PVCs are benign in y: There is no immediate danger to your life from pvcs which are considered benign in young people. If you are still concerned you need to seek advice from a cardiologist. I would advise you to avoid or minimize the use of coffee(tea and coke included), alcohol and smoking in the mean time. Daily exercise will also help you.

Could be panic: Attacks . Most pvcs among young folks are benign. I presume u had all the heart work up . Get reassurance from your cardiologist .Get checked for thyroid condition , pheochromocytoma, myopathy, myasthenia gravis etc quit smoking if u do, cut down on caffeine, soda and alcohol intake.
