the accuracy of left ventricular ejection fractions ( ef ) determined by multiple gated cardiac pool imaging ( ri-ef ) and by m-mode echocardiography ( echo-ef ) ( teichholz 's method ) was evaluated by comparing with those derived from angiocardiography ( lvg-ef ) in 19 patients including 9 with myocardial infarction , 3 with rest angina , 2 with effort angina , 2 with valvular disease , 1 with hypertrophic cardiomyopathy , 1 with congestive cardiomyopathy and 1 with hypertensive heart .
