本工作利用改进后的Langendorf哺乳类动物离体心脏灌流技术,对家兔离体心脏心电图记录作了探索性的研究。为了了解家兔离体心脏心电图的实际意义,我们在研究中改变了实验灌流条件或给予了人为的刺激动因,都明显地观测到相应的心电图图形的变化。这就有可能为某些急性心肌疾患的研究提供一个简易可行的实验手段。
In this work, the improved Langendorf mammalian isolated cardiac perfusion technique was used to explore the isolated ECG recording of rabbit heart. In order to understand the practical significance of rabbit isolated heart electrocardiogram, we changed the experimental perfusion conditions or given artificial stimulation motivation in the study, and observed the corresponding change of ECG pattern obviously. This may provide a simple and feasible experimental method for the study of some acute myocardial diseases.
