Variable atrioventricular block during atrial flutter: what is the mechanism? J Cardiovasc Electro- physiol 13: 950 -951, 2002.Duytschaever M, Dierickx C, Tavernier R. Variable atrioventricular block during atrial flutter: what is the mechanism? J Cardiovasc Electrophysiol. 2002;13:950- 951....
Because the AV node cannot conduct at the same rate as the atrial activity, some form of conduction block is often seen, typically 2:1 (most common), 3:1, or 4:1. This block may also be variable and cause atrial flutter to appear as an irregular rhythm. Twelve-lead ECG showing ...
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...

Variable AV block may also be due to other mechanisms (e.g., AV Wenckebach), producing non-integer ratios of F waves to QRS complexes (Fig. 15.5). Atrial flutter with 1 : 1 AV conduction (Fig. 15.6), although uncommon, constitutes a medical emergency and is most likely in three ...
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...
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 flutter is a type of supraventricular tachycardia caused by a re-entry circuit within the right atrium
Atrial flutter : an irregular heart rhythm of the atria. It is classified as supraventricular tachycardia . Symptoms include palpitations . Complications include increased risk of stroke and heart failure . Key difference: Flutter is a regular rhythm whereas fibrillation is irregular. Paroxysmal supra...
