| Abstrakt: | Introduction: Premature ventricular contractions (PVCs) are among the most prevalent arrhythmias. PVCs lead to haemodynamically insufficient heartbeats. Their presence is considered rather insignificant, but this widespread assumption is not supported by research evidence. Cases: We present three cases of patients commonly seen in daily general practice, with a range of presentations, varying from incidental (harmless) PVCs to frequent and potentially symptomatic PVCs. Discussion: In more frequent PVCs (> 10% heart beats) fatigue and exertional dyspnoea may occur. When > 20% of heart beats are PVCs, patients may develop cardiomyopathy and heart failure. Incidental PVCs are harmless. Anti-arrhythmic drug treatment should be considered in case of frequent PVCs but also catheter ablation appears an effective treatment option. Conclusion: Altogether, PVCs may not be harmless, depending on their occurrence rate. Research data from primary care settings on epidemiology and natural course is needed. |
