Many friends will be confused: heart discomfort, how does the doctor judge the specific cause? Why is chest tightness, he does a color ultrasound line, I have to do contrast? What does each of these tests do? In fact, with the development of technology, there are more effective means to diagnose heart diseases. Usually, doctors will use one or more of the echocardiography, electrocardiogram, and coronary angiography to help determine what is wrong with the heart. Heart color Doppler ultrasound, also known as "heart color Doppler", can dynamically display the heart structure, heart beat and blood flow, and do the examination is very convenient, there will be no damage. The heart has four rooms the right and left atria and the left and right ventricles.
The rooms are separated by "walls" (heart muscle), and the doors (valves) are the channels through which blood travels. The size of the door and the thickness of the wall have a certain normal range. Heart color Doppler ultrasound can clearly find the heart structural abnormalities, such as the size of the chamber, the thickness of the interwall, and the presence of valve insufficiency, stenosis, prolapse, and the ability of the heart to pump blood. Some children are born with holes in the walls of their rooms - atrial septal defects, ventricular septal defects, which are commonly known as congenital heart disease.
The PATIENT THAT HAS HYPERTENSION, BECAUSE OUTSIDE LONG TERM HIGH PRESSURE LOAD, THE HEART MUSCLE BECOMES FAT, THE WALL IS THICKER AND THICKER, THIS IS HYPERTENSIVE HEART disease.
Some people because of infection, cause the door leaf rust - valve stenosis or incomplete closure, resulting in the door can not open and close smoothly, affecting the normal flow of blood, this is valvular heart disease. The ultrasound probe is like the camera lens, moving back and forth in the chest, can clearly show the various structures of the heart on the screen, and the related diseases have no place to hide in front of the heart color ultrasound.
Electrocardiogram, understand the heart rhythm of normal people's heart, beat 60 ~ 100 times per minute, in general, less than 60 times is bradycardia, more than 100 times is tachycardia. In addition to the number of beats, the rhythm of the heart is also very important. A normal person's heartbeat is as accurate as a clock. If it is fast and slow, it is often said to be an arrhythmia. Arrhythmias are likely to affect the heart's ability to supply blood. For example, the most common clinical arrhythmia, atrial fibrillation, brings the feeling of palpitation, shortness of breath, fatigue, and even dizziness. Ecg can be divided into conventional ECG and holter ECG. In the former, electrodes and a system of hand and foot leads are held to the skin for several minutes, and the instrument plots the electrical activity of the heart. Experienced doctors can use these curves to tell if the heart is beating in rhythm. The advantage of Holter is that it can monitor heartbeat for 24 hours.
After all, arrhythmia is often accidental, conventional ECG failed to capture the "disorder" in time, dynamic ECG relying on the all weather "squatting point", often can catch a current.
Electrocardiogram combined with troponin, myocardial enzyme examination, but often used to find out the terrorist of myocardial infarction! If the heart were a house, the coronary arteries would be the pipes that supply the house with oxygen. The coronary arteries are distributed outside the heart and provide a constant supply of oxygen and nutrients to the heart. Diabetes, hypertension, dyslipidemia, smoking, etc., will make more and more impurities in the blood vessels, and the water flow is more and more obstructed. Generally, if the water pipe is blocked by more than 50%, the body will show various clinical symptoms with chest pain as the main manifestation in the case of excitement and fatigue, which is coronary heart disease. At this time, it is necessary to slow down the deposition of intravascular impurities through drugs and lifestyle improvement.
If it's more than 75 percent blocked, and chest pain and tightness are significant, you may need to do a coronary stent implant -- to open the blocked vessel with a stent, or coronary bypass -- to take a piece of blood vessel from another part of the body or a vascular replacement to allow blood to pass through the new conduit, bypassing the stenosis and reaching the ischemic site.
What kind of examination can we know the condition of coronary artery? That's coronary angiography. It is currently the "gold standard" for the diagnosis of CHD. With contrast media, the thickness of the coronary arteries can be clearly visualized by the physician under X-ray to determine the subsequent treatment.
