| 摘要: |
| [目的]用心导纳微分环(CADL)对急性心肌梗塞(AMI)患者进行心功能检查,以便确定AMI患者的CADL变化与临床表现的关系.[方法]选择符合世界卫生组织(WHO)规定的AMI诊断标准的患者30例(男22例,女8例),对他们进行CADL的检测.[结果]30例AMI患者中有28例CADL的Ⅰ相面积及总环面积减小;Ⅰ相离心支出现切迹、缺蚀或波浪状改变;V相面积增大,环形变异率高达90%.[结论]CADL的环形变化可以较临床表现更早地发现心功能异常,对指导治疗具有积极的意义. |

| Abstract: |
| To check up the heart function for the acute myocardial infarction(AMI) patients using cardiac admittance difference loop (CADL),making certain of the relationship betwwen CADL change and clinical manifestation.［Method］ to select 30 patients who were in line with the AMI diagnosing standards regulated by the World Health Organization (WHO).(male:22 cases; female:8 cases). Being engaged in CADL detection. ［Result］ Among 30 AMI patients there were 28 cases whose phase I area and the whole loop area decrease, with phase I centrifugal branch cutting mark and defect etching or wave change appearing, phase V area increasing, altering rate of loop figure being as high as 90%. ［Conclusion］ More importantiy,the CADl loop figure change can show the abnormal heart function earlier than clinical manifestation, possessing significance for directing the treatment. |
