Determination of the necrotic mass in inferior myocardial infarct by standard electrocardiography

: A study of 28 patients with acute inferior myocardial infarction, who died 3 days after the attack, involved the comparison of necrosis weight data, as determined anatomically, with those obtained through the measurement of the R wave height and the Q wave (QS complex) depth, taken from standard leads and amplified remote leads from limbs. The comparison results suggest that intravital electrocardiographic determination of the necrosis weight is possible. A formula has been derived for the determination of the necrotized tissue weight (in grams) in patients with left-ventricular inferior infarction.
