本文应用彩色多普勒诊断技术（ＣＤＦＩ）对驻地（海拔３９８０米）高原心脏病（ＨＡＨＤ）患者的左心功能和血管总外周阻力的变化特点进行了研究。并初步探讨ＨＡＨＤ时左心功能改变的机制，为临床早期诊断和治疗提供可靠依据。按高原心脏病诊断标准〔１〕确诊的高原心脏病患
In this paper, the changes of left ventricular function and total vascular resistance in resident (3980 m above sea level) altitude sickness patients (HAHD) were studied by Color Doppler Diagnostic Technique (CDFI). And preliminary study of the mechanism of left ventricular dysfunction in HAHD provide a reliable basis for early clinical diagnosis and treatment. According to plateau heart disease diagnostic criteria 〔1〕 confirmed plateau heart disease
