What are the characteristic spatial vectorcardiogram findings in patients with posterior myocardial infarction?
Spatial vectorcardiograms demonstrate a characteristic upward displacement of the early QRS sÊ-loop in posterior myocardial infarction, which may be useful for diagnosis.
A study of 45 spatial vectorcardiograms of patients with posterior myocardial infarction revealed a characteristic upward displacement of the early portion of the QRS sÊ-loop. Changes in the later portion of the QRS sÊ-loop may occur as a result of infarction. The possible utilization of such findings in the diagnosis of infarction is discussed.
Burch et al. (Thu,) studied this question.
