A rhythmic collaboration: Key articles from IEMR for Norwegian Cardiologists caring for patients with PVCs

Premature ventricular complexes (PVC) is one of the most common ventricular arrhythmias encountered in clinical practice, and although most often benign, may cause debilitating symptoms, risk of left ventricular dysfunction, or life-threatening arrhythmias.
