BACKGROUND: The aim of the present study was to evaluate the changes of electrocardiographic (ECG) markers of right ventricular (RV) hypertrophy/overload in patients with chronic thromboembolic pulmonary hypertension (CTEPH) undergoing pulmonary endarterectomy (PEA). METHODS AND RESULTS: We evaluated 99 CTEPH patients who underwent PEA. P wave amplitude in DII, R wave amplitude in V1 and the number of patients with negative T wave in V1-V3 decreased significantly at 1month after surgery with no further change at 1year, in parallel with the rapid improvement in right heart hemodynamics. S wave amplitude in V1, R:S wave ratio in lead V6 and prevalence of SIQIII pattern improved significantly at 1year, in parallel with the progressive reverse remodeling of the right ventricle at echocardiography. CONCLUSIONS: The study shows that some of the ECG markers of RV hypertrophy/overload better reflect RV hemodynamic overload while others better reflect the pathologic remodeling of the right ventricle.
