Abstract

Echocardiograms of interventricular septal motion were recorded in patients with cardiomyopathy to learn if absence of a septal Q wave, "electrical silence," in the electrocardiogram is associated with a noncontracting, "mechanically silent," septum.

Patients with cardiomyopathy with absence of septal Q waves in the ECG had an associated absence of normal motion of the interventricular septum. As would be expected electrical silence of the septum was associated with mechanical silence. These findings indicated cardiomyopathic disease of the interventricular septum in these patients.
