VTA: ventricular tachyarrhythmias; no.: number; NA: not available; LGE: late gadolinium enhancement. Parentheses represent the range of values. Number of LGE segments and an entropy LL significantly differed between hypertrophic cardiomyopathy patients with and without a history of ventricular tachyarrhythmias.
