[Effect of propranolol on arrhythmia in individuals with false chordae in heart ventricles]

Abstract

In 4156 echocardiographic examinations, false chordae were observed in 91 persons (2.2%). It was shown that false chordae without evidence of traction caused no increase of the risk of development of ventricular arrhythmia (class II and over according to Lown). In 50% of persons with false chordae and the evidence of traction significant ventricular arrhythmia occurred. It was found that administration of the drugs with negative inotropic action may increase arrhythmia in persons with false chordae in the heart ventricles.
