Abstract Background: Pulmonary hypertension is a condition that involves the remodeling of right ventricle. Ongoing also associated with disease prognosis. During restructuring process, complex changes such as hypertrophy and dilatation may be reflected in electrocardiographic parameters. Objectives: Our study aimed to investigate relationship between prognosis parameters patients pulmonary arterial hypertension. Methods: The was designed retrospectively included diagnosed 2010 2022. were divided into two groups based on their survival outcome. Various parameters, including electrocardiographic, demographic, echocardiographic, catheter, blood compared groups. A p-value <0.05 considered statistically significant. Results: In multivariate Cox analyses, found independently 6-minute walk test, mean artery pressure, presence pericardial effusion, time beginning QRS peak S wave (RS time) (p<0.05 for each). Of all RS demonstrated best diagnostic performance (AUC:0.832). analysis, significant correlation when using cut-off value 59.5 ms (HR: 0.06 [0.02-0.17], p < 0.001). Conclusions: According results our study, longer poor We can obtain information about course simple, non-invasive parameter.
