肺动脉高压是诊断肺心病的重要指标。肺动脉高压与肺阻抗血流图及肺功能指标有密切相关关系,国内外学者已有报告。本文旨在应用反映右心及肺血管情况的肺阻抗血流图指标和反映肺结构及功能变化的肺功能指标一起来推测肺动脉平均压,探讨肺心病早期诊断的简便方法。
Pulmonary hypertension is an important indicator of pulmonary heart disease diagnosis. Pulmonary hypertension and pulmonary impedance blood flow maps and lung function indicators are closely related to domestic and foreign scholars have been reported. The purpose of this paper is to estimate the mean pulmonary artery pressure by using pulmonary impedance spectroscopy (HRP) index that reflects right ventricular and pulmonary vascular conditions and pulmonary function parameters that reflect changes in lung structure and function, and to explore a simple and convenient method for the early diagnosis of pulmonary heart disease.
