WebSep 29, 2024 · A premature ventricular complex (PVC, or premature ventricular contraction) is an extra electrical impulse arising from one of the heart's ventricles. This extra impulse happens before the next normal heartbeat has a chance to occur. PVCs are very common and often require no treatment unless they cause symptoms or occur frequently. Premature atrial contraction (PAC), also known as atrial premature complexes (APC) or atrial premature beats (APB), are a common cardiac dysrhythmia characterized by premature heartbeats originating in the atria. While the sinoatrial node typically regulates the heartbeat during normal sinus rhythm, PACs occur when another region of the atria depolarizes before the sinoatrial n…
WebA first-degree AV block occurs when electrical conduction through the AV node of the heart is delayed and the impulse between the atria and ventricles is slowed. However, there is no interruption in the conduction between the atria and the ventricles. With a first-degree AV block, this delay in conduction often presents due to a minor defect in ...
