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.
