Catheter ablation of atrial flutter using radiofrequency energy.
Sixteen patients with type I atrial flutter underwent an attempt at radiofrequency catheter ablation (8 women, 8 men, mean age 53 +/- 11 years). The primary criterion used to identify sites for radiofrequency energy delivery was the identification of a fractionated electrogram. Radiofrequency energy was delivered for 20 to 30 seconds. Radiofrequency catheter ablation was acutely successful in 1...

Radiofrequency Catheter Ablation. Radiofrequency catheter ablation techniques are becoming increasingly accepted as the therapy of choice for selected patients with symptomatic arrhythmias. The ability to titrate the power output using radiofrequency current has allowed these ablative techniques to be applied safely in a variety of arrhythmias. In many institutions, radiofrequency catheter abla...
متن کاملAblation of the atrioventricular junction with radiofrequency energy using a new electrode catheter.
Percutaneous catheter ablation using radiofrequency energy can be used to interrupt atrioventricular (AV) conduction in patients with supraventricular tachycardia refractory to drugs. Results of radiofrequency ablation of the AV junction using a custom-designed catheter with a large, 3-mm-long distal electrode, 2-mm interelectrode spacing, and a shaft with increased torsional rigidity were comp...

any importance to thallium data even in these young patients. Nevertheless, it is open to speculation whether this important subgroup is characterized by a special anatomical substrate' or pathophysiological mechanism leading to an extraordinarily high degree of subendocardial ischaemia. Mainly because of methodological problems, ambulatory ST-monitoring seems to be of limited value for ischaem...
متن کاملRadiofrequency Catheter Ablation and Antiarrhythmic Drug Therapy
Background—Information on comparative outcome between radiofrequency catheter ablation (RFA) and antiarrhythmic drugs (AADs) 1 year after randomization is important for clinical decision-making. Methods and Results—A total of 198 patients (age, 56 10 years) with paroxysmal atrial fibrillation were randomly assigned to RFA (99 patients) or to AADs (99 patients). We evaluated efficacy of RFA or A...
