[Body surface mapping in patients with hypertrophic cardiomyopathy (HCM)].

The purpose of this study is to investigate the electrocardiographic indices that estimate the site of myocardial hypertrophy and the presence of ventricular tachyarrhythmia in patients with HCM. This study included 43 patients, 11 of them had episodes of ventricular tachyarrhythmia (9; sustained ventricular tachycardia, 2; ventricular fibrillation). Three patterns of QRS isopotential map were observed, each was characterized with apical, septal, and dilated phase HCM. VAT in left lateral chest to left back was statistically longer in patients with ventricular tachyarrhythmia. QRS isopotential map was useful for estimating the site of myocardial hypertrophy, and VAT ischrone map was useful for predicting ventricular tachyarrhythmia in patients with HCM.
