Mechanical changes of left ventricle (LV) during reversible attacks of myocardial ischemia at rest in man were investigated by means of standard time-motion echocardiography which permits a beat by beat analysis. However this technique requires handling huge amounts of data, when long-lasting phenomena are considered. To analyze the trends of events occurring during transient ischemic attacks, storage, display and statistical evaluation of the data, an original approach was used which requires a digitizer and a minicomputer. This approach provides trends of values of wall thickness, percentage systolic thickening, wall motion and excursion, LV dimension, percentage fractional shortening and LV hemodynamics.

Abstract
Mechanical changes of left ventricle (LV) during reversible attacks of myocardial ischemia at rest in man were investigated by means of standard time-motion echocardiography which permits a beat by beat analysis. However this technique requires handling huge amounts of data, when long-lasting phenomena are considered. To analyze the trends of events occurring during transient ischemic attacks, storage, display and statistical evaluation of the data, an original approach was used which requires a digitizer and a minicomputer. This approach provides trends of values of wall thickness, percentage systolic thickening, wall motion and excursion, LV dimension, percentage fractional shortening and LV hemodynamics.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
