[Predictors of ventricular tachycardia in patients with mitral prolapse].
128 patients with primary mitral prolapse and 72 healthy controls were examined using noninvasive methods. The analysis of the findings revealed predictors of electric myocardial unstability: reduced variability of cardiac rhythm, diastolic left ventricular dysfunction, late ventricular potentials and growing dispersion of the Q-T interval. Detection of mitral regurgitation correlates with development of ventricular arrhythmia.
