OBJECTIVE To determine whether recording of the activation potential may be used as an isolated criterion to guide catheter ablation of atriofascicular Mahaim fibers. METHODS We studied 6 patients (5 females, mean age of 26 +/- 7.3 years) with paroxysmal tachycardias with a wide QRS complex, whose electrophysiological study diagnosed atriofascicular(More)
PURPOSE To evaluate the results of direct current catheter ablation of accessory pathways by mean of a new low energy power source. METHODS Catheter ablation was performed in 40 consecutive patients (23 male, mean age 31 +/- 11 years) with accessory atrioventricular pathways (AP) using a low energy DC power source. The electrophysiologic study and AP(More)
PURPOSE To evaluate the behavior of single chamber stimulation system, rate responsive with vibration sensing, taking into consideration the results of long term clinical follow-up. PATIENTS AND METHODS From september 1986 to april 1989, 70 patients received pacemakers with vibration sensing. Sixty four patients (91.9%) implanted Activitrax I model and(More)
PURPOSE To evaluate the long-term efficacy and safety at long term after atrioventricular junction fulguration (complete AV block induction, using high energy shocks, to control drug-resistant supraventricular tachyarrhythmias. METHODS Twenty-eight patients, 17 (60.7%) men, with mean age 48.1 years, were submitted to one up to six ablation sessions with(More)
OBJECTIVE To study a series of patients submitted to radiofrequency catheter ablation (RFA) of left accessory pathways (AP) using the transeptal approach (TSA) as compared to the conventional retrograde arterial approach (RAA). METHODS One hundred consecutive patients (56 male; mean age of 34.3 +/- 11 years) with 100 left APs (62 overt and 38 concealed)(More)
Electrophysiological procedures use high-cost multipolar electrode catheters which can be reprocessed. The reuse thereof has been performed by electrophysiology services in Europe, United States, Latin America and also in our midst. In fact, prior studies have proved that there is an actual cost decrease1,2 and have also attested to the safety and efficacy(More)
