Abstract 18323: Electrocardiographic Changes as a Predictor of Right Ventricle Dysfunction in Acute Pulmonary Embolism

Background: Acute pulmonary embolism (APE) is a common potentially life-threatening condition. Right ventricular (RV) dysfunction is associated with poor prognosis in patients with APE. However, there is lack of information regarding electrocardiographic (ECG) changes and its relationship with APE prognosis. The aim of this study is to describe the ECG changes in APE and evaluate their relationship with RV dysfunction as an indicator of poor prognosis. Methods: From January 2010 to February 2017 all patients admitted in our coronary care unit (CCU) with APE were included. A multivariate logistic regression analysis was made to evaluate the relationship between ECG changes and RV dysfunction parameters in transthoracic echocardiogram (TTE). Results: 226 patients were included, 57.1% were female, mean age was 74.5 years (IR: 61- 81). At admission ECG and TTE were performed in all patients. The most frequent ECG findings at admission were Negative T waves, S1Q3T3 pattern and sinus tachycardia, in a 49%, 44% ...
