Scope note: Contracciones atriales rápidas e irregulares causadas por un bloqueo de la conducción del impulso eléctrico en el atrio derecho y un frente de ondas reentrantes que viajan hasta el tabique interatrial y la pared libre del atrio derecho o viceversa. A diferencia de la FIBRILACIÓN ATRIAL, que está causada por una generación anormal de impulsos, el aleteo atrial típico está causado por una conducción anormal del impulso. Al igual que en la fibrilación atrial, los pacientes con aleteo atrial no pueden bombear de modo efectivo sangre a las cavidades inferiores del corazón (VENTRÍCULOS CARDÍACOS).

Scope note: Rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up the inter-atrial septum and down the right atrial free wall or vice versa. Unlike ATRIAL FIBRILLATION which is caused by abnormal impulse generation, typical atrial flutter is caused by abnormal impulse conduction. As in atrial fibrillation, patients with atrial flutter cannot effectively pump blood into the lower chambers of the heart (HEART VENTRICLES).
