title: Heart synchronized gamma - camera gating: displaying two heart cycles on one screen.
abstract: A method for the evaluation of the haemodynamic status of a patient with acute myocardial infarction is presented. Left ventricular ejection fraction has been considered to be an accurate indicator of haemodynamic status before and after therapy. A device for synchronising the R-wave, and controlling the recording oscilloscope during systole and diastole is described. The intention is to display both systole and diastole on one oscilloscope.
