Abstract

Premature ventricular complexes (PVC) are frequently asymptomatic and do not require antiarrhythmic treatment. Outflow tract PVC are the most common idiopathic PVC in clinical practice. The anamnesis, physical examination and electrocardiogram are essential in the diagnosis of these patients. Although PVC of the ventricular outflow tracts are considered benign, they can produce various symptoms such as dyspnea on exertion, asthenia, palpitations, dizziness, presyncope or syncope, and in those patients with very high arrhythmic burden (>24% on a 24-hour Holter monitoring), can trigger extrasystole-induced cardiomyopathy, leading to deterioration of left ventricular systolic function and ultimately heart failure. When pharmacological treatment of PVC fails, ablation of arrhythmias by radiofrequency catheter is the only effective alternative. This is the case of the 62-year-old female patient, hypertensive, dyslipidemic and a smoker, which demonstrates the safety of radiofrequency catheter ablation, the therapeutic efficacy, and the complete restoration of the ventricular function of the heart.
