The research of anti-myocardial ischemia medicine is always a main part of research and development of new medicine of cardiovascular system. In this research field, experimental animal model of ligating amterior decdnding branch of coronary artery to cause myocardial ischemia of Beagle dogs is an important and commonly used experimental model. Its main indexes are Epicardium Electrocardiogram, II Connection Electrocardiogram, Enzymology and percentage of Infarction etc. Graph of Epicardium Electrocardiogram is more sensitive and accurate than surface II Connection Electrocardiogram (after ligating amterior decdnding branch of coronary artery, surface II Connection Electrocardiogram presents ischemic, but decreases quickly. There is no ischemia of real model animals now. However, Epicardium Electrocardiogram presents myocardial ischemia correct and stable). Graph of Epicardium Electrocardiogram is a way to get the range of myocardial infarction which can observe drug's potency intuitionally. The range of myocardial infarction and the degree of myocardial infarction are important indexes of the development of anti-myocardial ischemia medicine. It is better to provide experimental items when new anti-myocardial ischemia medicine is declared.
The product is made for collections of Epicardium Electrocardiogram. (1), XW-1 product aims at multi-channel biopack and sixteen-channel biopack. It is designed in the light of different collection interfaces. The collection is stable without random signal. (2), XW-2 is simple and commonly used. It can connect Single Channel Electrocardiogram Unit and complete collecting electrocardiograms like Epicardium Electrocardiogram and II Connection Electrocardiogram with one electrocardiogram unit. The signal is recorded on electrocardiogram paper after narrowing. The read and collection of data is convenient and reliable. There is no random signal after several tests. (3), XW-3 is a popular Four-channel Physiological Recorder (Tme) for present medical schools and research institutes, convenient and reliable.
Performance Index
Channel One: Ordinary Electrocardiogram for dogs.
Channel Two: Artery Blood Pressure.
Channel Three and Four: Epicardium Potentials of different parts.
The left picture shows the normal figure. The right picture shows the figure of ligating coronary artery in fifteen minutes.
From pictures we know it is hard to see myocardial ischemia from common electrocardiograms. But it is clear to see from epicardium potentials of different parts
Observation of epicardium potential is already an essential index in the research of new medicine of cardiovascular class.
