Abstract
Three patients were referred for urgent investigation and treatment of refractory arrhythmias. Each patient had failed to respond to antiarrhythmic drugs and in two patients direct current cardioversion was also unsuccessful. Transvenous ablation of atrioventricular conduction was therefore thought appropriate. With a temporary ventricular pacing system in situ, a second electrode was used to record His and atrial electro-grams. A 270 watt-second shock was delivered through this lead when the His potential was maximized. The tachycardia was controlled in two patients and the procedure was without deleterious effects.
