Paradoxical septal motion
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]
Overview
Paradoxical septal motion is defined as movement of the interventricular septum away from the left ventricular free wall during systole which is the opposite of its normal movement which is toward the free wall during systole.
Causes
- Arrhythmogenic RV dysplasia
- Following heart surgery. There may be altered LV function and lack of restraint on the pericardium if it is opened.
- Pericardial effusion (large)
- Right ventricular hypertrophy
Diagnosis
Echocardiography
