Key result
12-lead ECG abnormalities predict RV dilation in acute PE with up to 98% specificity.
Why the study?
Can 12-lead electrocardiographic abnormalities predict right ventricular dilation in patients with acute pulmonary embolism?
Observational (n=190)
Can 12-lead electrocardiographic abnormalities predict right ventricular dilation in patients with acute pulmonary embolism?
Electrocardiographic abnormalities demonstrate high specificity but variable and generally low sensitivity for predicting right ventricular dilation in patients with acute pulmonary embolism.
Answers are grounded in this paper and cite their sources.
ECG abnormalities' low sensitivity precludes reliable exclusion of RV dilation in acute PE; leaves open need for validation in prospective studies.
In a study of 190 patients with acute pulmonary embolism, right ventricular dilation was present in 64 (34%), mean age 58 +/- 15 years. The 18 electrocardiographic abnormalities on the 12-lead electrocardiogram had a sensitivity of 8-69%, a specificity of 70-98%, a positive predictive value of 23-69%, a negative predictive value of 64-83%, a likelihood ratio for a positive test of 1.3-4.4, and a likelihood ratio for a negative test of 0.41-1.10 in predicting right ventricular dilation in patients with acute pulmonary embolism.

Sukhija et al. (2005) conducted an observational in acute pulmonary embolism (n=190). 12-lead electrocardiogram abnormalities was evaluated on right ventricular dilation. 12-lead electrocardiogram abnormalities predicted right ventricular dilation in patients with acute pulmonary embolism with a sensitivity of 8-69% and specificity of 70-98%.
