Are premature ventricular contraction or ectopic heartbeats dangerous to me?

PVCs and MI: Premature ventricular contractions mean that there is irritability in the heart muscle and normal heart rhythm which starts from high up in the atria is inturrupted in some beats and those beats are originating in the ventricle.Bot it does not mean that it is directly due to mi.But you can get pvcs with mi.Occasional pvcs are not serious but if it comes from many foci and in runs it can be seriou.
