摘　　要：目的：研究高原性心脏病患者超声心动图与心电图肺型P波之间的临床变化关系。方法：收集高原性心脏病伴肺型P波的临床资料45例为高原性心脏病组；并按超声心动组诊断为右心扩大组26例、无心腔扩大组19例；在我院健康检查组30例为对照组；对其主肺动脉内径与肺型P波的变化进行比较。结果：高原性心脏病组主肺动脉内径较对照组显著增宽（P〈0．01）；高原性心脏病右心扩大组主肺动脉内径较无心腔扩大组显著增宽（P〈0．01）；无心腔扩大组肺型P波较右心扩大组显著增高（P〈0．05）。结论：心电图肺型．P波是诊断高原性心脏病右心扩大的敏感指标，超声心动图对高原性心脏病右心增大时可提供更为准确的依据。对于心电图提示肺型P波且心脏超声心动图显示右心腔扩大、有轻度肺动脉高压的患者应考虑移居至平原或较低海拔地区，也可采用间断或持续低流量（1L／分钟）吸氧，能明显改善患者的预后。Objective Research High altitude heart disease patients with echocardiography and electrocardiogram （ecg） type lung clinical changes of the relationship between P wave. Methods Collected the clinical data of type High altitude heart disease with pulmonary P wave 45 cases for High altitude heart disease group; And according to the ultrasonic echocardiography diagnosis of right heart expanded group 26 cases, centerless cavity expanding group （19 cases）; In our hospital health inspection group 30 cases as control group; The main pulmonary artery diameter and pulmonary P wave comparing with type pulmonary P wave changes. Results High altitude main pulmonary artery diameter was significantly faster than heart disease group （P 〈 0.01）; High altitude heart right heart to expand the main pulmonary artery diameter is centerless cavity expanding group widened significantly （P 〈 0.01）; Centerless cavity expanding group type pulmonary P wave is right heart expanded significantly higher （P 〈 0.05）. Conclusions Electrocardiogram（ecg） diagnosis of pulmonary P wave is High altitude heart right heart expanded sensitive indicators, echocardiography to right heart grows High altitude heart disease can provide more accurate basis.
