CORONARY ANATOMY AND THE 12-LEAD ELECTROCARDIOGRAM - HOW TO TELL WHO IS HURTING

Knowledge of how the coronary arteries, cardiac topography, and the 12 -lead electrocardiogram (EGG) link together is imperative if the elect rical tracing is to be interpreted correctly. Advanced practice nurses not familiar with the ECG may be intimidated by attempts to identify the disease process of myocardial infarctions. This article reviews co ronary anatomy and cardiac topography and then links them to the 12-le ad ECG for determining areas of myocardial ischemia, injury, and death . Copyright (C) 1997 by W.B.
