Objective(s) Electrocardiographic (ECG) changes in pulmonary embolism (PE) reflect right heart strain (RHS) and resolution may predict short-term outcomes. This study investigated ECG changes in patients with European Society of Cardiology intermediate-high and high risk PE, and evaluated if persistence of ECG changes after treatment predicted survival to hospital discharge. |

|
Material and Method Consecutive patients with intermediate-high risk and high risk PE, confirmed by CT pulmonary angiography, were recruited from an academic medical centre registry. 4 ECG parameters indicative of RHS at the time of diagnosis and after treatment of PE, which included thrombolysis and thrombectomy, were reviewed. Primary outcome was survival to hospital discharge. |

Result(s) The prevalence of ECG abnormalities in 71 patients is shown in the Table. The average age was 62.3 years ± 13.8, and 70.0% of the cohort was female. Following treatment, sinus tachycardia and S1Q3T3 persisted in 47% and 57% respectively (p<0.01). Persistence of ECG changes, however, did not predict survival to hospital discharge. Table.

Conclusion In patients with intermediate and high-risk PE, resolution of ECG changes with treatment did not predict survival to hospital discharge. |
