Case 27 Atrial flutter with 3 : 1 A-V blockdoi:10.1159/000429013E. K. Chung
Atrial flutter is a cardiac arrhythmia characterized by atrial rates of 240-400 beats/min, usually with some degree of atrioventricular (AV) node conduction block (eg, 2:1 or 3:1 block). Approximately 60% of patients with atrial flutter have coronary artery disease (CAD) or hypertensive ...
1. a regular, repeated pattern of sounds, stresses or beats in music, poetry etc. Just listen to the rhythm of those drums; complicated rhythms.ritmo 2. a regular, repeated pattern of movements. The rowers lost their rhythm.ritmo 3. an ability to sing, move etc with rhythm. That girl ...
Using a standardized induction protocol, we investigated the mechanism of initiation of atrial flutter, before ablation, to determine the site of initiating unidirectional block and to test the hypothesis that the direction of rotation of atrial flutter depends on the pacing site from which it initiat...
Atrial flutter is a type of supraventricular tachycardia caused by a re-entry circuit within the right atrium
An aged case of atrial flutter with complete A-V block was presented. This combination of arrhythmias was emphasized to be rare, and histological study of the conduction system revealed a fresh degenerative change superimposed on the severe degenerative and fibrotic changes at the penetrating portion...
1. to strike forcefully and repeatedly: to beat a toy drum. 2. to hit (a person or animal) repeatedly so as to cause painful injury; thrash (often fol. by up). 3. to dash against: rain beating the trees. 4. to flutter or flap: a bird beating its wings. 5. to sound, as ...

V-A and A-V Intervals During Atrial Flutter Ablation. Background: The success of cavotricuspid (CTI) ablation depends on the achievement of bidirectional block. Previous investigators have shown that right ventricular (RV) pacing can replace proximal coronary sinus (pCS) pacing in assessing clockwis...
Atrial fibrillation, also called A-fib, is the most common type of heart arrhythmia. In fact, A-fib affects an estimated 3-6 million people in the United States alone.1With A-fib, the upper heart chambers (the atria) beat irregularly. As a result, blood doesn’t move well into the ...
