Key result
Right-sided ST elevation is linked to ~8-fold higher 30-day mortality risk in acute pulmonary embolism.
Why the study?
Electrocardiographic studies are more feasible than CT angiography and echocardiography under emergent conditions in acute pulmonary embolism, but their diagnostic and prognostic value needs evaluation.
Does right-sided ECG improve diagnostic sensitivity and prognostic assessment in patients with acute pulmonary embolism compared to standard ECG?
Population
143 patients with confirmed acute pulmonary embolism
Comparison
Right-sided electrocardiogram vs standard electrocardiogram
Design
Observational study
Loading...
RS-ECG abnormalities were associated with RV strain and higher PESI; leaves open whether routine use improves emergent APE risk stratification.

Right-sided ECG offers higher diagnostic sensitivity than standard ECG for acute pulmonary embolism, and ST segment elevation on RS-ECG is a strong predictor of right ventricular dysfunction and higher mortality risk.
A 2021 study conducted an observational in Acute pulmonary embolism (n=143). Right-sided electrocardiogram (RS-ECG) vs. Standard electrocardiogram was evaluated on High 30-day mortality risk based on PESI score (OR 8.42, 95% CI 2.08-33.93, p=<0.05). ST segment elevation on right-sided ECG independently predicted high 30-day mortality risk (OR 8.42; 95% CI 2.08-33.93; P<0.05) and was associated with increased RV/LV diameter ratio in APE.
