Abstract;A ten-year-old female domestic shorthair cat was referred to the Azabu University Teaching Hospital with a four-week history of episodic syncope. Electrocardiography revealed Adam-Stokes syncope caused by a paroxysmal third-degree atrioventricular block. A permanent pacemaker implantation was performed to prevent further episodes. Inappropriate pacing like spikes on T, which might cause critical arrhythmias, was noticed immediately after implantation. Refractory-period reduction to minimize the likelihood of noise reversion during tachycardia, selection of bipolar pacing, and sensitivity adjustment eliminated the pacing problem. Nine months after the implantation, no further abnormal pacing had occurred. (author abst.)
