Precordial ECG mapping in acute myocardial infarction (AMI) after intravenous infusion of streptokinase (s).

Repeated precordial ECG mapping (42 leads) and CK-MB serum measurements were done in 40 patients with anterior and/or anterolateral acute myocardial infarction. Twenty patients serving as controls, were treated with routine anticoagulant therapy. In 20 patients (the s group), randomly selected, a short-term IV infusion of 1,500,000 IU streptokinase was administered and followed by the same anticoagulant treatment as in controls.
