Comparison of the informative value of electrocardiographic criteria of myocardial infarction with the use of different lead systems.
The authors compared the informative value of 39 criteria of myocardial infarction with ECG registration using the standard 12-lead system (ECG-12), 24 criteria according to Frank's orthogonal system (OECG-F), and 32 criteria according to the new 4-lead system (ECG-4). 127 patients with myocardial infarction (MI) were examined. The sensitivity of the most informative ECG-4 criteria of MI was higher (44.4%) than OECG-F (39.4%) and ECG-12 (38.6%). With the application of quantitative ECG-4 criteria, signs of MI were detected in all cases diagnosed by experts using the ECG-12 system. In view of the considerable simplicity of its registration technique, the ECG-4 system can be recommended for the mass screening ECG examinations aimed especially at detection of MI.
