Premature ventricular complexes (PVCs) are a common finding in general population and can be even considered physiologic in most cases. Nevertheless, very frequent isolated PVCs may lead to the development of a usually reversible left ventricular dysfunction or be a manifestation of an underlying cardiac condition that could be associated with more severe ventricular arrhythmias, heart failure or cardiac death.
Three causative mechanisms of the PVCs have been proposed: abnormal automaticity, triggered activity and reentry supposing different diagnostic and therapeutic implications.
Although many patients with PVCs remain completely asymptomatic, others may suffer from a wide range of symptoms like palpitations, fatigue, dyspnoea or dizziness of a variable degree.
Proper characterisation of the PVCs, their burden and features, as well as the identification of their sites of origin and mechanisms should be pursued to establish the convenience of a conservative or therapeutic approach.
Specific treatment with medical therapy or catheter ablation must be contemplated in symptomatic patients or in those who develop related systolic dysfunction or other kind of complications.
