Factors determining the success of a single, low-energy, direct current-shock to achieve
chronic complete heart block were studied in a consecutive group of 14 patients. A shock of …

Catheter‐induced His bundle ablation for refractory supraventricular arrhythmias is most
commonly performed with direct‐current shock energy of 200‐300 joules. The high energy …

Ninety-three patients, who underwent DC shock ablation were reviewed over a mean follow-
up period of 54 months (range 3 to 84 months). These patients (46 male and 47 female …

The utility of high-frequency current applied through the distal electrode of a conventional
electrode-catheter for altering atrio-ventricular conduction was studied in 18 anaesthetized …

Alteration of atrioventricular (AV) conduction was attempted in 7 consecutive patients with
severely symptomatic, drug-refractory supraventricular tachyarrhythmias using low-energy …

Gonzales et al.[l] first demonstrated in animal experiments that permanent complete heart
block could be achieved by delivering high energy direct current shocks to the His Bundle …

Three shocks of 2 joules (2.000 volts within 0.3 msec) were given to a patient with ventricuiar
tachycardia of right ventricuiar origin at the site of the earliest activation. A standard 6 Fr …

Six patients were referred for investigation and treatment of refractory arrhythmias. Each
patient had failed to respond to antiarrhythmic drugs and transvenous ablation of …

The need to develop an experimental model in the closed chest animal for the study of
hemodynamic and electrophysiologic effects of various physiologic and pharmacologic …

Catheter ablation using direct current (DC) shock has proved invaluable in the management
of a variety of tachycardias. However, sporadic reports of fatal arrhythmias following ablation …
