Abstract Pulmonary hypertension(PH) is a pathophysiological state in which pulmonary vascular resistance progressively increases due to the contraction and pathological remodeling of pulmonary arterioles, eventually evolving into right heart failure and death. Right heart catheterization is the gold standard for the diagnosis of PH, whereas it is invasive and risky of potential complications. Electrocardiogram (ECG) as a convenient routine examination plays an important role in guiding the diagnosis, and treatment and prognosis evaluation of PH, although it can not directly reflect the level of pulmonary artery pressure.
