  • Title: Electrocardiography in myocardial infarction.
    Author: Madias JE.
    Journal: J Electrocardiol; 1979 Oct; 12(4):411-23. PubMed ID: 390078.
    Abstract:
    Electrocardiography is an evolving clinical diagnostic modality for detection of acute myocardial infarction. Animal studies and electrocardiographic-clinical-pathological correlations have provided experience currently used for detection and rough localization of myocardial infarcts. Additions to the conventional 12 electrocardiographic leads have been utilized to increase the diagnostic sensitivity of the ECG in the setting of myocardial infarction. Mapping of ST-segment elevation an QRS complex from several chest wall loci have been employed for purposes of quantitating serially myocardial ischemic injury and eventual necrosis. These multiple lead electrocardiographic systems have also been utilized in assessing therapeutic interventions in the Coronary Care Unit. Usefulness of standard and multiple-lead recording systems is enhanced by awareness of their limitations when applied to patients with acute myocardial infarction.
