MSH: An autosomal dominant defect of cardiac conduction that is characterized by an abnormal ST-segment in leads V1-V3 on the ELECTROCARDIOGRAM resembling a right BUNDLE-BRANCH BLOCK; high risk of VENTRICULAR TACHYCARDIA; or VENTRICULAR FIBRILLATION; SYNCOPAL EPISODE; and possible sudden death. This syndrome is linked to mutations of gene encoding the cardiac SODIUM CHANNEL alpha subunit.,NCI: A condition characterized by a pattern of right bundle branch block (RBBB) and ST-segment elevation within electrocardiogram (ECG) leads V1-V3 . This pattern emerges as a result of a defect in ion channel genes, resulting in abnormal electrophysiological activity in the right ventricle and a propensity to malignant tachyarrhythmias.
