ECG is the most well-known kind of thermal paper. ECG can make a clear diagnosis on the origin of cardiac excitation and conduction function, that is, arrhythmia. , congenital heart disease, electrolyte disorders and other diseases, can provide a strong diagnostic basis, so closely linked with various disciplines, is the most basic clinical examination technology.
ECG information management system, also known as ECG network system. He realized the digital storage of all the original ECG data by computer, so that the patient's ECG data can be permanently saved. Traditional ECG charts are thermal paper. Over time, ECG charts become blurry and unclear, and single pages are easily lost. For patients undergoing ECG examinations, the results of each examination are saved on the computer, which is helpful for doctors to compare the ECG examination results of patients, find out the patient's condition in time, and make a correct diagnosis. Each ward of the hospital is equipped with an ECG machine. Inpatient patients can complete the ECG examination at the bedside, and the examination results are transmitted to the ECG room through the network. , so that patients can receive timely treatment.
What are the examination items in the ECG room?
1. Conventional 12-lead ECG
2. 18-lead ECG
Completing the 18-lead ECG at one time, compared with the 12-lead, the posterior wall and right ventricle examinations are added, so that the blood supply of the heart can be more comprehensively reflected, and the diagnosis of coronary heart disease, myocardial infarction and other diseases can be more comprehensive and accurate.
3. Dynamic ECG
Holter, also commonly known as wearing box, Holter, 24-hour dynamic, is mainly used to monitor arrhythmia, angina pectoris and transient syncope, and to qualitatively and quantitatively analyze the captured arrhythmia, guide clinical medication, and observe drugs The efficacy of the pacemaker can be assessed for patients with pacemaker.
4. Ambulatory blood pressure
Ambulatory blood pressure is a detection technology that automatically, intermittently, and regularly measures blood pressure in daily life through instruments. Generally, it is measured once every half an hour during the day and once an hour at night, which can more objectively reflect the actual level and fluctuation of 24-hour blood pressure. High-risk patients are more advantageous.
Diagnostic criteria: The most valuable and commonly used indicators are the average systolic and diastolic blood pressure levels during the 24-hour day (wake activity) and night (sleep). Percentage of nocturnal blood pressure drop and early morning blood pressure rise.
The average 24-hour daytime and nighttime blood pressure reflects the overall level of ambulatory blood pressure in different stages. The upper limit of normal reference for ambulatory blood pressure is 24h<130/80mmHg daytime<135/85mmHg nighttime<120/70mmHg.
5. Plank exercise test
The treadmill exercise test is to increase the load of the heart through a certain amount of exercise, and observe the changes of the electrocardiogram. It is mainly used for clinical identification of chest pain, diagnosis of coronary heart disease, observation of drug efficacy, guidance of rehabilitation exercise for heart patients, and physical examination in special industries.
Analysis of the contents of the ECG report
1. Sinus rhythm
The general commander of the heart beat is the sinoatrial node, and the sinus node issues commands to form a heartbeat, which is called sinus rhythm, so sinus rhythm is synonymous with normal heart rhythm.
2. Sinus arrhythmia
In fact, sinus arrhythmia is not a disease, but a physiological phenomenon. It is common in children and young people, and decreases with age. There are few symptoms of discomfort, no obvious clinical significance, and generally does not require special treatment.
3. Premature beats
Don't be nervous first, the appearance of premature beats is related to many factors, such as non-cardiac disease, mental stress, sleep conditions, physical stress response, etc. A small amount of premature beats will not have obvious effects on the body, but if the symptoms of palpitations are obvious, Holter monitoring can be done to assess the number of premature beats in 24 hours, and consult a clinician on how to deal with it.
4. ST-T exception
When you see the ST-T changes that often appear in the ECG report, everyone will be very nervous. Am I suffering from myocardial ischemia or coronary heart disease? In fact, ST-T abnormality is affected by many factors, such as autonomic dysfunction, non-cardiac disease, so don't deduct coronary heart disease on yourself when you get such a report, you need to find a cardiologist and listen to the doctor's advice for further examination.
5. The electrocardiogram is normal, do I need to do other inspection items?
Yes, echocardiography looks at the structure of the heart, atrium, the size of the ventricular cavity, the closure of the heart valve, and the function of the heart. Coronary CT scans the heart for atherosclerosis and stenosis.
6. Do I need to fast for an ECG?
You don't need to be fasting for an ECG, you can come anytime, but remind everyone to go to the hospital to see a doctor and try to wear simple, separate clothes to facilitate the examination.
