Specific Study on VCG Diagnose of Canine Myocardial Infarction / 中国医学物理学杂志

ABSTRACT

Objective: Tracing the 15 leads electric signal of canine myocardial infarction by means of VCG and ECG ,compar-ing the diagnose standard of VCG and ECG ,confirm the difference of diagnose standard of canine myocardial infarction ,vali-date 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 diag-nose myocardial infarction than ECG.
