摘　　要：目的 研究右胸电导纳容积波法估测左心室舒张末压(LVEDP)的应用价值.方法 对20例经冠状动脉造影证实的冠心病患者于左心导管检查后24～72小时进行右胸电导纳容积波检查,与20例健康对照者比较,并分析心导管测值与右胸电导纳容积波参数的相关性,结果 本组患者LVEDP平均为2.65±0.64KPa(19.9±4.8mmHg),右胸电导纳容积波参数冠心病组与健康对照组比较有显著差别,与LVEDP有较好的相关性(r=0.55～0.85,P<0.01～0.001,S=4.90～9.52)结论 右胸电导纳容积波法是一种无创估测LVEDP的有用方法.Objective To evaluate the applicability of right chest electricadmittance plethgsmography (RCEAP) to estimating left ventricular end diastolic pressure (LVEDP).Methods Twenty patients with coronary heart disease (CHD) confirmed by coronary angiography were examined with RCEAP and compared with twenty healthy volunteers (as control). Correlation was analyzed between LVEDP measured by left heart catheterization and the parameters of RCEAP. Results Mean LVEDP was 2.65±0.64KPa (19.9±4.8mmHg). A significant difference existed between the RCEAP parameters from patients with CHD and those from normal sudjects. The correlative coefficients between LVEDP and RCEAP parameters indicated 0.55-0.85 (P<0.01- 0.001 and sx=4.9-9.5). Conclusion RCEAP is a useful noninvasive method for the estimation of LVEDP.
