Premature ventricular contractions (PVCs) are common heart rhythm issues, often benign but sometimes indicating serious cardiac disease. This review covers their causes, prevalence, and management for general physicians.
Area of Science:
- Cardiology
- Internal Medicine
- Electrophysiology
Background:
- Premature ventricular contractions (PVCs) are prevalent in 3%-20% of the general population.
- Often detected during evaluations for palpitations or incidentally on ECG.
- While typically benign, PVCs can signify underlying cardiac disease and cause debilitating symptoms.
Purpose of the Study:
- To provide a comprehensive review of PVCs for internists.
- To cover the etiologies, epidemiology, evaluation, and management of PVCs.
- To highlight the relevance of PVCs in primary care and general medicine settings.
Main Methods:
- Literature review of existing studies and clinical guidelines on PVCs.
- Synthesis of information regarding the prevalence, causes, and clinical significance of PVCs.
- Discussion of diagnostic approaches and therapeutic strategies for managing PVCs.
Main Results:
- PVCs are common and frequently encountered in non-specialist settings.
- A significant minority of PVCs may be associated with structural heart disease.
- Effective management strategies exist for symptomatic or concerning PVCs.
Conclusions:
- Internists play a crucial role in the initial identification and management of PVCs.
- Understanding the diverse etiologies and implications of PVCs is essential for appropriate patient care.
- A systematic approach to evaluation and management ensures optimal outcomes for patients with PVCs.
