A Case of a Short-Coupled Variant of Torsades De Pointes with Electrical Storm
2003
TAKEUCHI, T., et al.: A Case of a Short-Coupled Variant of Torsades De Pointes with Electrical Storm.This case report describes a short-coupled variant of Torsades de Pointes with a characteristic ECG pattern consisting of a prominent J wave in leads V3–V6, in which an electrical storm was evoked with autonomic receptor stimulation and a blockade test. The patient's frequent VF attacks were triggered by short-coupled premature ventricular contractions with a right bundle branch block morphology and left-axis deviation, and were suppressed by deep sedation followed by a combination therapy using verapamil and mexiletine. Interestingly, with the use of those drugs, the prominent J wave diminished. The mechanism underlying this syndrome is discussed. (PACE 2003; 26[Pt. I]:632–636)
