Description
Technical field
The present invention relates to Diagnosing Coronary Artery instrument technical fields, more particularly to a kind of eight channel coronary artery diseases to examine
Disconnected instrument.
Background technique
Cardiovascular disease is currently the first big killer in China or even the world.Since 99% thrombus in clinic is not appoint
What symptom and feeling, or even by the routine inspection of hospital's cardiovascular and cerebrovascular training, the indexs such as blood lipid, blood pressure, electrocardiogram are also shown
Show normally, so the performance of sufferer myocardial infarction is unobvious routine diagnosis, rapid onset, death rate height, blood is via two masters
It wants coronary artery to enter heart, and via a blood vessel network on cardiac muscle surface, heart is made to obtain nutrient.Cholesterol,
Fat deposition is formed in the artery, makes channel narrows, and such case is referred to as atherosclerosis.In the blood of arterial flow
It will form a kind of thrombus, obstruction of artery got up.When physiology or psychology are under pressure, heart can jump fastlyer, need more
More oxygen and nutrient, this is a kind of situation that coronary artery is unable to cope with when seriously narrowing or being blocked.As a result it causes
Coronary insufficiency leads to angina pectoris or pained.Flow to cardiac muscle blood due to one coronary artery of thrombus obstruction and
It largely reduces, will have a heart attack, referred to as coronary arteriosclerotic cardiopathy suddenly, since 99% thrombus in clinic is not have
There are any symptom and feeling, or even passes through the routine inspection of hospital's cardiovascular and cerebrovascular training, the indexs such as blood lipid, blood pressure, electrocardiogram
It also shows normally, so the performance of sufferer myocardial infarction is unobvious routine diagnosis, rapid onset, death rate height.At present medically
Quick diagnosis is carried out to coronary heart disease without a kind of simple and fast means.
Although existing stethoscope, stethoscope, which carries out heartbeat sound analysis, cannot diagnose some heart diseases.It can not
Allow analyst can obtain caardiophonogram (PCG) signal qualitative and quantitative feature and they may be comprising abnormal heartbeat
Sound, such as the position of heart sound S1 and S2 and noise and the cardiovascular system under the conditions of different pathological caused by distortion.In addition,
The physical characteristic of sound and human auditory from research heart can see, and the ear of people is to be not suitable for cardiac auscultation, with auscultation
The ability of the sound of device clinical diagnosis heart is limited, for this purpose, we have proposed a kind of eight channel Diagnosing Coronary Arteries
Instrument solves the above problems.
