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...
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. 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 ...
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...

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...

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...
palpitate, flutter - beat rapidly; "His heart palpitated" thrash - beat so fast that (the heart's) output starts dropping until (it) does not manage to pump out blood at all beat - indicate by beating, as with the fingers or drumsticks; "Beat the rhythm" ...
Patients with left or right bundle branch block, atrioventricular block, atrial fibrillation, atrial flutter, ventricular arrhythmia or structural heart disease were excluded from the study. Standard electrocardiography criteria were used to diagnose atrial fibrillation12 and atrial flutter,13 consistent with...
