Electrocardiographic findings associated with early clinical deterioration in acute pulmonary embolism

Abstract

SVT was an independent predictor of CD. TWI V_2-4 , iRBBB, STE aVR, sinus tachycardia, and S1-Q3-T3 were independent predictors of abnlRV. Finding one or more of these ECG patterns may increase considerations for performance of echocardiography to look for RV abnormalities and, if present, inform concerns for early clinical deterioration.
