Atrial Flutter with Spontaneous 1:1 Atrioventricular Conduction in Adults: An Uncommon but Frequently Missed Cause for Syncope/Presyncope Aims: To compare patients with atrial flutter (AFl) and 1:1 atrioventricular conduction (AVC) with patients with AFl and higher AVC. Methods: The charact... G...
Atrial Flutter Atrial flutteris due to a reentrant circuit revolving around thetricuspid valvethat causes a rapidatrial tachycardia. Atrial flutter can initiate in fetal life and result infetal hydrops. Atrial flutter can have variable conduction, with 2:1, 3:1, or 4:1 block referring to the ...
Atrial Flutter with 1:1 A-V Conduction Atrial flutter usually occurs with some degree of A-V block; however, uncommonly it occurs without A-V block, i. e., with 1: 1 A-V conduction. This is an i... J Marks - 《A.m.a.archives of Internal Medicine》 被引量: 9发表: 1957年 ...

During all the episodes of stable atrial flutter, a line of functional block with a mean length of 24 +/- 4 mm was localized on the right atrial free wall. When the previously stable line of functional block decreased to a mean of 16 +/- 3 mm (P or = prior length) to create a ...
The risk factors for and the symptoms and causes of atrial flutter are similar to those of atrial fibrillation. For example, strokes are also a concern in someone with atrial flutter. As with atrial fibrillation, atrial flutter is usually not life-threatening when it's properly treated. Risk ...
1 patient with , 2 with + AV (spontaneous ventricular rate less than 45 bpm) and 3 with AV needed ventricular backup-pacing during AF. In 7 patients a total of 15 attacks of atrial flutter could be terminated by atrial overdrive pacing, in 5 of these episodes by temporary high rate ...
