Outflow tract ventricular Arrhythmias: When and how to treat?

In the 1970s, many studies demonstrated that premature ventricular contractions (PVCs) were associated with up to a 3-fold increase in mortality in patients with prior myocardial infarction.[1-2] In subsequent decades, several large series also demonstrated that even in apparently healthy people, this association is still present.[3] When more detailed analysis focuses on specific characteristics of PVCs, the association becomes more nuanced. A study of exercise-induced PVCs demonstrated that patients with RBBB or multiple morphology PVCs had increased mortality, but patients with a LBBB morphology alone had unchanged mortality.
