Occaisional PVC's are really nothing to worry about. They are common and even expected in the super atheletes. The marathon runners have a very low heart rate
and frequent PVC's.
When you have to do something is when they happen enough that it causes you be be dizzy or light headed. Then they can give you a medication to help out.
The other time that is significant is when there are a bunch of them connected to gether, this is called V-tach, (ventricular tachycardia
) and then something needs to be done.
Just follow your doctors advice and relax...
