Background: The aim of the present study was therefore to evaluate the evolution of electrocardiography (ECG) markers indicator of morbidity and mortality after pulmonary endarterectomy (PEA). It may be a good predictor of mortality and morbidity in chronic thromboembolic pulmonary hypertension (CTEPH) with patients who underwent PEA. PEA may be reduced risk of arrhythmia in patients with CTEPH. However, this claim must to be supported with long-term results. Materials and Methods: We collected demographic, ECG, and echocardiographic parameters data (baseline and after the operation) in patients undergoing PEA for CTEPH at our institution from 2009 to 2013.We assessed 62 CTEPH patients who underwent PEA. Results: P wave amplitude in DII, PR interval, P and QT dispersion changed significantly at 3 months after surgery. The P dispersion (17.66 ± 6.2, P < 0.04) and QT dispersion (23.75 ± 11.37, P < 0.015) were longer in before operation than in after operation. Conclusions: In our study, we found in ECG analyses of CTEPH with patients who are undergoing PEA that P dispersion, QT dispersion were changed when compared with before operation. For this reason, we think that PEA reduces the risk of atrial fibrillation and malignant arrhythmia.
