Transient atrioventricular block following catheter radiofrequency sinus node modification
Cardiol J 2007;14(5):504-507.
Abstract
Complete atrioventricular block, second-degree Mobitz type II and first-degree atrioventricular
block with right bundle branch block were observed consecutively following successful
radiofrequency ablation in close proximity to the sinus node. This resulted in the modification
and disappearance of the inappropriate sinus tachycardia that had previously been present.
Neither tachycardia nor conduction disturbances have been recorded in the 9-year follow-up,
implying that ventricular pacing standby should also be considered in high atrial ablation
cases. (Cardiol J 2007; 14: 504-507)
