title: Role of electrocardiography in identifying right ventricular dysfunction in acute pulmonary embolism.
abstract: The role of electrocardiography in identifying right ventricular (RV) dysfunction in acute pulmonary embolism (APE) was evaluated in 81 patients with APE. The electrocardiographic markers studied were T-wave inversion in leads V1 to V3, the S1Q3T3 pattern, right bundle branch block, and sinus tachycardia. T-wave inversion in leads V1 to V3 had the greatest sensitivity and diagnostic accuracy for identifying RV dysfunction in patients with APE. The S1Q3T3 pattern and right bundle branch block had good specificity but moderate accuracy.
