What is useful to get back to a normal heartbeat? I am experiencing PVC and it is lasting longer than in the past. It is erratic, 1 skip and 2 beats or more at random, and also short periods of normal in between. It never lasted more than one day or less in the past, but this is now the 4th day. ( I injured my rib under the right arm 6 days ago. Could that contribute to this?)
