心阻抗血流图是反映心脏血液动力学变化,评价心血管病变患者心功能的一种无创伤性检查方法。对于动脉导管未闭(PDA)患儿手术前后心阻抗图及其微分图的改变,目前报告较少,现将我院1986～1987年6月间10例PDA患儿手术前后心阻抗图的变化报道如下。一、资料和方法经本院儿科心血管专业门诊系统体格检查,胸部X线摄片、心电图、超声心动图检查,且手术证实为
Cardiac impedance blood flow diagram is a noninvasive test method that reflects cardiac hemodynamic changes and assesses cardiac function in patients with cardiovascular disease. For patients with patent ductus arteriosus (PDA) before and after surgery in patients with heart impedance diagram and the changes in the differential graph, the current report is less, now in our hospital from 1986 to 1987 June 10 cases of PDA before and after surgery in patients with heart impedance changes Reported as follows. First, the data and methods The hospital pediatric cardiovascular professional out-patient physical examination, chest X-ray, ECG, echocardiography, and surgery confirmed
