What is CRT? What does CRT stand for in medicine

Cathode tube radiographic display!

It's one of those big displays!

CRT to put it simply

It's the kind of thing that is very common on the market

Flat, very large display kind.

Cathode tube radiographic display!

In RTS mode, C stands for pampering.

Life education. The core concept of "love is life".

The basic model of life education: "care, record, thanksgiving, and share", referred to as "CRTS model".

This core is related to the four relationships of heaven, man, matter, and self. That is, everyone should care, record, be grateful, and share love and life, and everyone should care, record, be grateful, and share the relationship between life and heaven and me.

Basic Information. In the most fundamental sense, life education is a kind of whole-person education.

It covers the whole process of human beings from birth to death and all aspects involved in this process, which is not only about human survival and life, but also about human growth and development, and more importantly, about human nature and value.

Life education is not only the premise of all education, but also the highest pursuit of education. Therefore, life education should become an important educational concept that points to the ultimate care for people.

It is put forward on the basis of a full investigation of the essence of human life, in line with the requirements of human nature, and it is a kind of humanistic education that comprehensively cares for life at multiple levels.

CRT refers to cardiac resynchronization**, which refers to the asynchronous contraction of the left and right ventricles when the heart has intraventricular block (the indication is complete left bundle branch block), and an artificial three-chamber pacemaker (right atrium, right ventricle and left ventricle) is implanted to achieve sequential atrial ventricular pacing and synchronized contraction of the left and right ventricles, and the ejection fraction of the heart is improved from the stool. CRT-D combines defibrillation function (CRT + ICD) on the basis of CRT, that is, in addition to achieving simultaneous contraction of both ventricles, it also has defibrillation function. The core component of the cathode ray tube display is the cathode orange coarse ray tube and picture tube.

It works on the same principle as the CRT display in our home TV[1]. We can think of it as a TV with a clearer image.

CRT stands for cardiac resynchronization**, when the heart has ventricular block (the indication is complete left bundle branch block), the left and right ventricles contract asynchronously, and an artificial three-chamber pacemaker (right atrium, right ventricular Yuanjing, left ventricle) is implanted to achieve atrial ventricular sequential pacing and synchronized contraction of the left and right ventricles to improve cardiac ejection fraction.

CRT-D is based on CRT and takes into account the defibrillation function (CRT + ICD), that is, in addition to achieving simultaneous contraction of both ventricles, there is also defibrillation function.

CRT is short for Cardiac Resynchronization**. CRT (cardiac resynchronization) is a small electronic device used for heart failure, and it is currently the most effective way to achieve heart failure. CRT achieves optimal atrial ventricular sequential activation through biventricular pacing to increase diastolic filling time, help synchronize left and right ventricular contractions, reduce mitral regurgitation, and increase stroke volume.

Effectively help the heart provide enough force to pump blood throughout the body, increase cardiac output, improve cardiac function, and gradually return the heart to normal size, thereby achieving heart failure**. CRT (cardiac resynchronization**) has been shown to improve symptoms, improve quality of life, delay disease progression, improve prognosis and reduce mortality in people with heart failure.

Doctors recommend that patients with cardiac insufficiency despite medications**, New York cardiac function class II-IV, low ejection fraction on cardiac ultrasound or cardiac magnetic resonance, and widened QRS duration on ECG, recommend that CRT** be accepted as soon as possible. According to statistics, more than 70% of patients with heart failure benefit from CRT**. CRT (cardiac resynchronization**) is of great significance for reversing ventricular remodeling, improving cardiac function, improving exercise tolerance and quality of life, and reducing hospitalization and mortality rates of heart failure.

crt（cathode

raytube) is a cathode ray tube. It is a widely used display technology. The CRT projector decomposes the input signal source into the phosphor screen of the three CRT tubes: R (red), G (green) and B (blue), and the luminous signal is amplified and converged under high pressure, and the color image is displayed on the large screen.

CRT is Chongqing Rail Transit, which refers to the urban rail transit serving the Chongqing metropolitan area of Hengshou China.

Chongqing Rail Transit Line 2 is the first straddle monorail in China and the first urban rail transit line in western China.

Chongqing's urban rail runs through mountains and mountains, crosses two rivers, and shuttles between streets and alleys and buildings, becoming a unique landscape and a "business card" of the city, as well as a "fast lane" to promote development and facilitate the people.

Medically CRT is a CRT display waiter. The scientific name is "cathode ray picture tube", and it is a display that uses a cathode ray tube. It is mainly composed of five parts:

Electron guns, deflectioncoils, shadowmasks, high-voltage graphite electrodes and phosphor coatings, and glass housings.

CRT displays, like other hardware devices, often fail. However, the survey found that only about 20% of failures were actually due to poor quality or natural damage, and that the majority of failures were due to poor environmental conditions and improper operation or poor management. It can be seen that environmental conditions and human factors are the main causes of display failure.
