Echocardiographic examination revealed in 184 (11%) of the 1680 persons an accessory chorda in the left cardiac ventricle (ACLV). It was found ACLV was often associated with paroxysms of cardiac of unclear etiology and ventricular fibrillation in myocardial infarction. The clinico-, phono-, electrocardiographic symptomatology and inheritability of ACLV are discussed. As defined by the authors the syndrome in ACLV includes: 1) cardialgia, 2) systolic murmur, 3) electrocardiographic syndrome of early ventricular repolarization, 4) paroxysms of cardiac fibrillation, 5) Predisposition to ventricular fibrillation in myocardial infarction.
