WebApr 8, 2024 · Premature atrial contraction frequency was not associated with memory or language factor scores. When we modeled PAC frequency continuously, each 1% higher PAC frequency was associated with a lower executive function score by 0.02 (95% CI, 0.04 to 0.01) and a lower global factor score by 0.02 (95% CI, 0.03 to 0.00). 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…

WebDec 2, 2024 · P wave morphology. The P wave typically has a different morphology and axis to the sinus P waves; PACs arising close to the AV node (“low atrial” ectopics) cause retrograde activation of the atria, producing an inverted P wave with a relatively short PR interval ≥ 120 ms (PR interval < 120 ms is classified as a PJC); The abnormal P wave may … WebJul 21, 2016 · Premature Ventricular Contractions (PVCs) Fetal PVCs are considerably less common than PACs. The PVC is not preceded by a normal atrial beat. In isolation, PVCs should be monitored regularly, but intervention is usually not required.
