[Tendinous cords in echocardiographic studies--occurrence, clinical significance].
Tendinous chords inside cardiac ventricles were found in 53 (5.6%) out of 954 individuals examined echocardiographically within one year. Only 30 individuals were further analysed. No marked pathology in the cardiovascular system was found. Tendinous chord was localized in the right ventricle in 7 individuals, in left ventricle in 21, and in both ventricles in 2 subjects. Ventricular arrhythmias were shown in 11 subjects (36.6%) with the aid of a 24-hour ECG monitoring with Holter's technique. They were of the II and IV stage of advancement according to Lown's classification. Ventricular rhythm disorders were seen in both subjects with tendinous chord within left ventricle (7 subjects) and in the right ventricle (4 subjects). Local diastolic disorders with no effect on the ejection fraction were noted in all subjects with false chord and ventricular rhythm disorders. Ventricular cardiac rhythm disorders are being observed in the subjects with the false chord located within the right or the left cardiac ventricle producing local diastole disturbances.
