We often hear people say that their hearts are uncomfortable. When we go to the hospital and face Linglang's full range of examination items, what do we need to do? What should we look at the project inspection results last night?
There are many examination items, and cardiac ultrasound is one of them. Cardiac ultrasound is a common non-invasive imaging examination method in clinical practice. In addition to examining basic conditions such as heart size, structure, and systolic function, it also has certain reference value for diagnosing heart diseases.
1、 Working principle of cardiac ultrasound
Cardiac ultrasound is an examination item that uses ultrasound technology to dynamically detect the heart. It uses mechanical waves such as ultrasound to propagate through the human body, encountering different tissue densities, reflecting back different sound waves, and finally converting them into images through electronic technology for display on the screen. This is the principle of ultrasound operation
2. The role of cardiac ultrasound
There are many functions of cardiac ultrasound, mainly used to diagnose whether there are abnormalities in cardiac hemodynamics, whether there are acquired lesions in cardiac structure, evaluate cardiac function, determine cardiac tumors and thrombosis, and whether there is congenital heart disease.
3、 Advantages and disadvantages of cardiac ultrasound
(1) Advantages
1. Cardiac ultrasound is a non-invasive examination method that does not cause any trauma or damage to the examiner and has high safety.
2. Cardiac ultrasound can intuitively display the structure and movement of the heart, helping doctors to clearly observe the subtle structures of the patient's heart, such as chambers, valves, and blood vessels.
3. Cardiac ultrasound also has the advantages of high reliability, reproducibility, accuracy, and stability.
4. Cardiac ultrasound can be used for the examination of various heart diseases, such as cardiomyopathy, valve disease, coronary heart disease, etc. It can also be used to evaluate heart function and pericardial effusion, with a wide range of applications.
（2） Disadvantage
1. The detection rate of foramen ovale is reduced due to factors such as acoustic window and false echo loss.
During the examination process, patients are required to maintain a quiet state and not move their bodies to avoid affecting the accuracy of the examination results.
3. For special cases such as severe arrhythmia, heart valve stenosis or regurgitation, cardiac ultrasound may be limited or affect the accuracy of the examination results.
4、 Precautions for cardiac ultrasound examination
(1) Pay attention to diet
Before undergoing the examination, the examinee should maintain a normal diet, avoid overeating, and avoid consuming stimulating foods and drinks.
（2） Comfortable to wear
The examinee should wear loose and comfortable clothing to facilitate changing positions and movement during the examination.
（3） Adequate Rest
The examinee should ensure sufficient rest, avoid participating in vigorous exercise before the examination, maintain a calm mood, avoid emotional excitement, and avoid affecting the examination results.
（4） Cooperate with the doctor
The examinee should actively cooperate with the doctor during the examination process, follow the doctor's instructions, maintain calm breathing, avoid moving the body, and avoid interfering with the examination results.
（5） Pay attention to medication side effects
If the subject is taking medication before the examination, they should truthfully inform the doctor and ask if it is necessary to stop taking or adjust the medication dosage before the examination.
5、 Target population for cardiac ultrasound examination
(1) Heart disease patients
Cardiac ultrasound can accurately evaluate the structure and function of the heart, helping doctors diagnose heart diseases such as cardiomyopathy, valve disease, coronary heart disease, and other heart diseases.
（2） Hypertension, diabetes, obesity and other high-risk groups
These groups are prone to cardiac complications. Cardiac color ultrasound can evaluate the structure and function of the heart, and prevent and treat heart diseases.
（3） People who frequently experience cardiac discomfort and those who have undergone cardiac surgery or intervention treatment
People who frequently experience symptoms such as chest tightness, palpitations, chest pain, dizziness, and those who have undergone cardiac surgery or intervention treatment need to undergo regular cardiac ultrasound examinations to evaluate the effectiveness of the surgery or treatment.
（4） Pregnant women
Some pregnant women also need to undergo cardiac ultrasound examination during pregnancy to evaluate the structure and function of their heart and ensure the health of both mother and baby.
The importance of cardiac ultrasound as a fundamental examination is self-evident. So cardiac ultrasound examination cannot be ignored or replaced.
