  • Title: Precordial ST-segment mapping 5. Analysis of maps and standard electrocardiograms in patients with inferior myocardial infarction.
    Author: Madias JE.
    Journal: J Electrocardiol; 1978 Oct; 11(4):369-74. PubMed ID: 712287.
    Abstract:
    Measured and derived electrocardiographic parameters pertaining to ST-segment elevations, R and Q wave amplitudes from standard electrocardiograms, and 49-lead precordial maps from ten patients with acute inferior transmural myocardial infarction were analyzed. Sums of ST-segment elevations correlated well with corresponding values derived from various combinations of standard leads expressing inferior ischemic injury. Derived ECG R and Q wave data from maps did not correlate with corresponding parameters from the standard ECGs. Stability of parameters derived from ST-segment elevations over the course of the study and lack of correlation with data expressing changes in the R and Q waves were noted. An analytical pattern such as the one utilized in this study can be used for assessment of therapeutic interventions in the Coronary Care Unit.
