What is the treatment of.Pvcs in both venyricles?
Most require nothing
It is unclear by your statement what you mean by both ventricles, ie multifocal? In any event, assuming they are a symptomatic and there is no other evidence of heart disease like cardiomyopathy or other conditions like hyperthyroidism, then treatment is not required.
There are medical treatments such as calcium blockers, beta blockers and more potent antiarrhthmics if necessary.
