本文对慢性呼吸衰竭患者(基础疾病主要为肺结核后遗症),在稳定期及急性进行期检查心电图,并讨论与平均肺动脉压和血气及预后的关系。67例分为2组。Ⅰ组42例,于稳定期进行右心导管检查,测肺动脉压、动脉血气分析以及用热稀释法测心搏出量。检测前描记12导联心电图。Ⅱ组25例,在急性期及稳定期行动咏血气分析,同时描记12导联心电图。稳定 In this paper, patients with chronic respiratory failure (underlying diseases mainly tuberculosis sequelae), ECG examination in the stable and acute phase, and discuss with the average pulmonary arterial pressure and blood gas and prognosis. 67 cases were divided into two groups. In group Ⅰ, 42 patients underwent right heart catheterization in stable period. Pulmonary arterial pressure, arterial blood gas analysis and cardiac output were measured by thermal dilution method. Pre-test description of 12-lead electrocardiogram. Ⅱ group of 25 cases, in the acute phase and stable operation of the operation of blood gas analysis, while tracing 12-lead ECG. stable
