[Premature ventricular complexes: what to do?]

Premature ventricular complexes (PVCs) are frequently encountered arrhythmias in the general population. They can occur in the context of an underlying structural heart disease (SHD) of ischemic, hypertensive or inflammatory cause and therefore be a prognostic factor. Some PVCs can appear in the context of inherited arrhythmic syndromes while others are seen as idiopathic in the absence of an underlying heart condition and are considered benign. Those idiopathic PVCs often arise from the ventricular outflow tracts, mostly from the right ventricle outflow tract (RVOT). The PVCs burden even with no underlying SHD can be associated with PVC-induced cardiomyopathy which is a diagnosis of exclusion.
