[Value of the electrocardiogram to predict the pattern of left ventricular contraction in ischemic cardiopathy].

A correlative electrocardiographic and ventriculographic study was performed in a series of 100 patients with clinical and electrocardiographic diagnosis of ischemic heart disease. The analysis was focused on the possibility of predicting ventricular contraction pattern (VCP) disturbances, through electrocardiographic signs of coronary insufficiency. Two main groups were separated on the basis of the presence of necrosis. There were 66 cases with necrosis, and 34 without it. The type of VCP was calssified in accordance with the criterion of Herman et al. in: asyneresis, akinesis and dyskininesis. The degree of coronary narrowing was arbitrarily evalued as less than 50%, between 50 and 75%, and over 75% of the lumen.
