摘要
目的:利用心电向量图(VCG)与心电图(ECG)两种方法同步描记犬出现心肌梗塞时的15路体表心电信号,通过对VCG和ECG两种诊断指标的对比,确定VCG和ECG诊断犬心肌梗塞的差异,并验证VCG对犬心肌梗塞诊断的特异性。方法:通过对30只正常犬的冠状动脉结扎,人为造成心肌梗塞,记录犬出现心肌梗塞时的15路体表心电信号,并进行对比分析。结果:VCG对犬心肌梗塞的诊断敏感,诊断指标提前出现,诊断特异性明显地高于ECG。结论:对犬心肌梗塞的早期诊断,采用VCG和ECG两种诊断方法,VCG的特异性高于ECG。
Objectlve： Tracing the 15 leads electric signal of canine myocardial infarction by means of VCG and ECG ,comparing the diagnose standard of VCG and ECG, confirm the difference of diagnose standard of canine myocardial infarction ,validate the diagnosing specificity of canine myocardial infarction. Methods： Make an operation of coronary artery ligation on 30 healthy dogs to make a myocardial infarction model, record the 15 leads information of ECG and VCG from body surface ,then contrast and analyse them. Results： The sensitivity diagnosing to canice myocardial infarction by VCG is much higher and more specific than that by ECG. Conclusions： Diagnosing early by means of VCG and ECG, VCG is more specific to diagnose myocardial infarction than ECG.
