Abstract

The authors report the unique case of remote onset of exercise induced focal ventricular tachycardia in a 40-year old male patient that originated from the ventricular end of an accessory atrioventricular pathway 18 months after a successful ablation. There was no residual conduction across the pathway after the first ablation. The ventricular tachycardia (VT) was mapped to and successfully ablated at the same site where the ventricular end of the pathway was previously ablated. The VT morphology was similar to that of the pre-excited QRS beats noted before. Thus far, in all reported cases of accessory pathway related automaticity there was intact conduction over the pathway or acute injury to it. To the best of our knowledge a case similar to our patient is not yet reported.
