cardiography

A total of 109 patients underwent physical examination, electrocardiogram and echo cardiography.

总计109个病人做了体格检查, 心电图,超生心动图.

Objective To Validte the Yeliabil of left ventricle ejection fraction ( LEF ) measured by reconstructed impedance cardiography ( RICG ).

目的验证重建心阻抗图测量左室射血分数 ( LEF ) 的可靠性.

Methods Forty-one patients ( 52.3 ± 9.8 years) with Q wave myocardial infarction underwent low-dose dobutamine electrocardiography and echocardiography before revascularization, revascularization was performed in all patients. Resting echocardiogram was repeated two month after revascularization.

方法41例近期心肌梗死患者，于血管重建术前行低剂量多巴酚丁胺超声心动图（Low-DoseDobutamineEchocardiography，LDDE）和负荷心电图检查，术后两个月重复静息超声心动图检查。
