Abstract: | In this case study we report a 59-year-old man who underwent combined aneurysectomy, endocardial resection, and cryosurgery for recurrent ventricular tachycardia. Following surgery he developed an accelerated junclional tachycardia with rates up to 190/min arising near the area of cryoablation which involved the junctional region. Using intracavitary recording and stimulation this tachycardia was shown to arise from ihe junctional area and had characteristics suggesting accelerated automaticity. During the electrophysiological study the focus of the tachycardia was temporarily obtunded by catheter trauma. After reappearance of the arrhythmia, successful suppression was achieved using diphenylhydantoin. (PACE, Vol. 5, May-June, 1982) |
