Atrial flutter rates increased during exercise testing in four patients. Improved A-V conduction with consequent higher ventricular rates occurred during exercise in thirteen subjects. One patient, with 4:1 conduction at rest, continued with 4:1 block throughout exercise testing, was believed to be...
1. movement or procedure with uniform or patterned recurrence of a beat, accent, or the like. 2. a. the pattern of regular or irregular pulses caused in music by the occurrence of strong and weak melodic and harmonic beats. b. a particular form of this: triple rhythm. c. rhythm ...
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...
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 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 ...
Catheter ablation of typical atrial flutter: a randomized comparison of 2 methods for determining complete bidirectional isthmus block. Complete bidirectional isthmus conduction block (CBIB) was initially assessed by sequential detailed activation mapping at both sides of the ablation line ... Anselme,Savo...
195: Women with atrial flutter differ from menThe management and prognosis of heart diseases (HD) or arrhythmias may depend on the patient gender. The purpose of the study was to look for the influence of gender on the indications and the long-term results of ablation of atrial flutter (AFl...
As with atrial fibrillation, atrial flutter is usually not life-threatening when it's properly treated. Risk factors Certain factors may increase your risk of developing atrial fibrillation. These include: Age.The older you are, the greater your risk of developing atrial fibrillation. Heart disease...
