question: I wore a holter monitor for 48 hours. I had 15 triple pvc s and 12 double pvc s during that time. I also experienced a reverse electrical shock. it started in my chest and went down my left arm. Felt just like 120 volt shock does but in reverse. My arm was numb and felt as if it went to sleep for several minutes after the shock. I had a full stress test with no signs of heart damage. I have a long family history of heart disease.
