Atrioventricular block during radiofrequency catheter ablation of atrial flutter: incidence, mechanism, and clinical implications.
AIMS To evaluate the incidence, mechanism, and clinical implications of atrioventricular (AV) block during catheter radiofrequency (RF) ablation of the cavotricuspid isthmus (CTI). Although RF ablation of atrial flutter is the most frequently performed ablation procedure, data on the incidence and significance of an AV block occurring during the procedure are scarce. METHODS AND RESULTS Conse...
متن کاملAtrial flutter with exit block.
The mechanism of atrial flutter is controversial. A 76-year-old woman with rheumatic heart disease was referred to our clinic with an unusual rhythm disturbance which initially appeared to be classic atrial flutter at a rate of 300 beats/min. Later tracings, however, demonstrated a rate exactly one-half that of the earlier ECGs, with an identical p-wave morphology and vector. This latter rhythm...

AVNRT, (Atrioventricular nodal reentry tachycardia), atrial tachycardia and atrial flutter are 3 kinds of supraventricular tachycardia, which their mechanism are explained based on reentry. A 60-years-old man is presented with all of the above-mentioned arrhythmias, responsive to intravenous injection of adenosine. Radiofrequency ablation of the slow pathway territories cured all of them. There...
متن کاملTransvenous ablation of atrioventricular conduction with a low energy power source.
A power source modified to increase voltage delivery and minimise arcing (for a given energy) was used for transvenous ablation of atrioventricular conduction to control refractory supraventricular arrhythmias in 14 patients. Twelve had atrial fibrillation or flutter, one had atrioventricular nodal reentry tachycardia, and the other had permanent junctional reentry tachycardia. Despite treatmen...
متن کاملRadiofrequency catheter ablation for supraventricular tachycardias: experience at Peshawar.
BACKGROUND Drug therapy is mostly employed in the management of supraventricular tachycardias (SVTs). However, radiofrequency catheter ablation has been found to be highly effective and safe in the treatment of SVTs. The current study is aimed at sharing our experience of 320 patients who presented with SVTs, and were treated with radiofrequency catheter ablation. METHODS This descriptive stu...
