Abstract
A retrospective analysis of the changes in ST segment and T wave was made in 35 patients (16 male, 19 female) with massive pulmonary embolism in whom the diagnosis was confirmed at autopsy. Parameters of the last 2 ECG available were measured and compared. During massive pulmonary embolism the most characteristic abnormalities were a decrease in ST segment, which took place in about 70% of measurements in leads I and V5-V6. Another common change was the inversion of the T wave, which took place in 43% in aVF [augmented unipolar ECG leads (left foot)] and in 37% in lead II.
