Premature Atrial Complex (PAC) • LITFL • ECG Library Diagnosis
Oct 8, 2024 · A premature atrial complex (PAC) is a premature beat arising from ectopic pacemaking tissue within the atria. There is an abnormal P wave, usually followed by a normal QRS complex. AKA: Atrial ectopics, atrial extrasystoles, atrial …
Ventricular Premature Complexes - StatPearls - NCBI Bookshelf
Apr 3, 2023 · Ventricular premature complexes (VPCs), or premature ventricular complexes/contractions (PVCs), are ectopic beats that arise from within the ventricles. They are common and can occur in a wide variety of clinical scenarios and a diverse population.
Premature atrial contraction - Wikipedia
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 ...
