Conference paper


An automated videoangiocardiographic system has been developed and used for the study of dynamic internal left ventricular geometry, in 53 patients (12 normals, 20 patients with different degrees of left ventricular [LV] pressure-, and 8 with LV volume overload. 9 patients had different types of cardiomyopathy and 4 atypical or failing LV). From the measurements of ejection phase parameters of contraction, the degree of endsystolic and enddiastolic excentricity of the LV, the ejection fraction, and the circumferential fiber shortening or shortening velocities it has been shown that there are no signs of impaired left ventricular function in mild and moderate left ventricular hypertrophy due to pressure or volume overload.
