 wow.. how often does this happen? 
 Rarely these days, but they used to happen multiple times a week for period of a couple years. I could feel the electricity shock my heart. 
 I've had something like this since I was a kid - sudden strong tingling in my arms and upper body and resulting jerks of the muscles - but nothing that approaches the violent bodily shock that we see here. I've always wondered what it was. For years I thought I eas just very sensitive to "tickling". 
 It could possibly be very mild seizures.
