The prevalence and the prognostic value of microvolt T-wave alternans in patients with hypertrophic cardiomyopathy.

BACKGROUND Nonsustained ventricular tachycardia (nVT) may have ominous implications for patients with hypertrophic cardiomyopathy (HCM). The microvolt T-wave alternans (TWA) has been proposed as a noninvasive tool-identifying patients at risk of sudden cardiac death and ventricular tachycardia/fibrillation (VT/VF). The aim of the study was to determine the… CONTINUE READING
