This block may also be variable and cause atrial flutter to appear as an irregular rhythm. Twelve-lead ECG showing atrial flutter with variable block. View Media Gallery Atrial flutter can arise from conditions that lead to atrial dilatation. These include chronic left-sided congestive heart ...
21-5). Postoperative atrial flutter typically has 2:1 conduction. If antiarrhythmic drugs have been given as part of routine prophylaxis, the ventricular rate with 2:1 block may be less (125 to 150 beats per minute). Atrial flutter with 2:1 AV block can be difficult to distinguish from ...
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...

atrial flutter (Figure 1) with variable AV conduction, multifocal atrial tachycardia (Figure 2), and wandering atrial pacemaker. Conversely, a regular pulse or rhythm does not exclude AF. For example, AF can manifest with a regular ventricular response in the presence of AV block or with a ...

36 Occasionally, other arrhythmias such as frequent irregular premature atrial beats and atrial tachycardia (AT)/flutter with variable ventricular response can falsely give the impression of AF. A more careful examination of the EKG, focusing on atrial activity, can be helpful in such cases. The ...
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...
