摘要
本研究应用M型和二维超声心动图观察了20例正常人、15例心绞痛患者食道调搏前后的心功能改变。结果是,正常人调搏后DE斜率,EF稍增加(P<0.05);ESV缩小(P<0.05);EF斜率呈稍增加但无统计学意义(P>0.05)。心绞痛患者调搏后DE斜率、EF斜率、EF降低(P<0.05),EPSS、ESV稍增加(P<0.05)。表明:食道调搏负荷试验能使心绞痛患者心功能降低,而对正常人心功能则无影响。因此,此法可用于评价静息时心功能正常的冠心病患者的心功能。
Left ventricular function was evaluated with M-mode echocardiography and two-dimensional echocardiography at rest and after transesophageal atrial pacing in 15 patients with angina pectoris and 20 normal persons. Result showed that D-E slope of anterior mitral valve increased(P<0.05), end systolic volume decreascd(P<0.05)and election fraction slightly increased (P>0.05) after pacing in normal persons. On the contrary, D-E slope and ejection fraction decreased (P<0.05), and E-point septal sep, ration and end systolic volume increased (P<0.05) after pacing in patients. The results suggest that transesophageal atrial pacing stress echocardiography can accurately evaluate left ventricular function for patients with coronary artery disease.
