I have pvcs when i am relaxing, exercising and even post exercise. i had a stress test(came out perfectly normal) but i still get pvcs? dangerous?

Unlikely. Unstress!: In someone of your age it is unlikely to be of clinical importance. Often psychological stress may be a factor. Keep track of the frequency (pvc's per 5 minutes) and see if periods of anxiety, anger, fear, or depression correlate with higher frequency. Learn deep relaxation/meditative skills (see drmiller.Com), stay in good aerobic cardiorespiratory shape, and stop worrying.
