[Computer tomographic evaluation of left ventricular kinetics].

The judgment of the function of the left ventricle is computer-tomographically possible using the ECG-regulated cardio-computer-tomography in a temporary resolution of about 0.1 sec. The qualitative and quantitative evaluation of the systolic and diastolic changes of the ventricle in patients with normal CT-findings, with idiopathic hypertrophic subaortic stenosis and with disturbances of motility in chronic ischaemic heart disease confirms the possible functional evidence known from literature. The quantitative parameters, in particular the systolic abbreviation of the axis, allow an estimation of the motility. The measurement of the thickness at the interventricular septum and at the lateral wall of the myocardium as well as the systolic abbreviation of the axis and the left-ventricular ejection fraction are essentially higher in the idiopathic hypertrophic subaortic stenosis than in the normal group. The values of the patients with disturbances of motility in the ischaemic heart disease were clearly below. The diagnosis of the idiopathic hypertrophic subaortic stenosis with response of the size of obstruction by the telesystolic and telediastolic pictures is possible in a high percentage. Sequelae of the chronic ischaemic heart disease, e.g. scars, become visible by a narrowing or an absence of the normal edge of the myocardium. Global and localized disturbances of motility are diagnosable by phase-referred systolic and diastolic ECG-regulated pictures.
