  • Title: The hyperacute phase of right ventricular infarction.
    Author: Lewis BS, Rozenman Y, Ben-David Y.
    Journal: Heart Lung; 1984 Nov; 13(6):682-4. PubMed ID: 6567641.
    Abstract:
    In summary, the hyperacute phase of RV infarction presents three possible patterns on the surface ECG (Fig. 3): the typical repolarization picture of hyperacute myocardial infarction, with slope elevation of the ST segment and tall T waves; rounded elevation of the ST segment, where the typical changes are "damped" by negative or posterolaterally directed, LV repolarizing forces; and ST elevation concave upward in the right chest leads, where anteriorly directed, underlying left ventricular ST segment and T wave vectors enhance the hyperacute picture.
