Abnormal diastolic motion of interventricular septum during inspiratory phase. Echocardiographic study.
We report on a patient without heart disease who had pulsus paradoxus, associated with echocardiographic evidence of abnormal and exaggerated diastolic motion of interventricular septum. Both phenomena appeared at the peak of the inspiratory phase of respiration, and seemed to be produced from the same haemodynamic variations, of which the echocardiographic pattern appears to be a more sensitiv...
متن کاملEchocardiographic Demonstration of Abnormal Motion of the Interventricular Septum
A characteristic abnormality of motion of the interventricular septum was recorded by echocardiography in 17 of 18 patients with left bundle branch block. Early and abrupt contraction of the septum occurs during the pre-ejection period before the delayed commencement of contraction of the posterior wall of the left ventricle. This abnormality can be explained by asynchronous contraction of the ...
متن کاملAbnormal Motion of the Interventricular Septum
ume overload was created in open-chest dogs by pumping blood from the left atrium to the right atrium. In seven of eight dogs changes in interventricular septum motion were produced acutely at shunt flow as low as 500 cc/min. When the shunt was decreased or stopped, interventricular septum motion returned to normal. Shunts producing left ventricular volume overload (aorta to left atrium and rig...

متن کاملAn echocardiographic study of the interventricular septum in constrictive pericarditis.
Ten patients with constrictive pericarditis were studied echocardiographically with specific reference to inter-ventricular septal dynamics. Abnormal movement of the interventricular septum was present in 8 patients and consisted of flattening in systole and unusual posterior motion in diastole. The aetiology of this type of movement is at present unknown but may be related to restriction of no...
