常规心电图检查在肺高血压诊断与评估中的应用

Application of routine electrocardiogram examination in the diagnosis and evaluation of pulmonary hyper-tension

肺高血压(pulmonary hypertension,PH)是一种由于肺小动脉收缩和病理性重构并逐渐闭锁,导致肺血管阻力进行性升高,最终发展为右心衰竭和死亡的病理生理状态。右心导管检查是诊断PH的金标准,但有一定的创伤性且有潜在并发症。心电图作为一种便捷的常规检查,虽然不能直接反映肺动脉压力水平,但在PH的诊断、疗效及预后评估中均具有重要的指导意义。

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.
