As we get older, this examination must be taken seriously! Protect the heart from heart disease

The electrocardiogram is probably one of the most familiar tests.

Although familiar with nouns, many people do not really understand the meaning of electrocardiograms. A friend left a message saying:

The various curves of the electrocardiogram are really incomprehensible. I don't know what those professional terms mean

In fact, watching electrocardiograms is an absolute technical task, and it requires accumulating rich clinical experience. Some non cardiologists are not necessarily very clear about their judgments. If you are not a doctor, there is no need to ask yourself to "read the electrocardiogram.".

However, as a common and basic examination, health headlines (WeChat: Baojiandaifu) believe that it is necessary to understand the following five common knowledge about electrocardiograms.

As you get older, you should pay more attention to ECG examination

It is recommended that the following people undergo an electrocardiogram during physical examination:

Elderly people over 60 years of age;

Patients with chronic diseases such as hypertension, diabetes and hyperlipidemia;

A perennial smoker.

"The probability of heart disease among these groups of people is significantly higher than among others, and it is very necessary to have regular electrocardiogram examinations.".

Is the electrocardiogram a discharge to the heart?

The beating of the heart is accomplished by the electrical signals of the relevant myocardial cells. An electrocardiograph can record these signals and express them through curves, which are commonly seen in electrocardiograms.

The electrocardiograph itself does not discharge outward, it is only used to record the electrical activity of the heart itself.

Therefore, doing an electrocardiogram does not cause damage to the heart, so there is no need to be nervous.

If there is a problem with the heart, the electrical signal of the heart will appear abnormal, and the curve of the electrocardiogram will be different. Doctors can use different curves to determine whether a patient has a heart problem and what is wrong.

What does "sinus heart rate" mean?

Electrocardiogram reports vary in length, with some reports directly stating "normal electrocardiograms," while others are a collection of jargon that cannot be understood.

For example, in many reports, the first sentence is "sinus rhythm." Many people are puzzled. What is this?

"Sinus rhythm" refers to the sinus node, an anatomical structure of the heart. Sinus rhythm is a signal that directs the beating of the heart and is initiated by the sinus node, which is the origin of normal heartbeat.

The heart beat must start from the "sinus node", otherwise it is an abnormality or disease.

To put it simply, sinus rhythm is the rhythm of the normal beating of the heart. Seeing this word indicates that there is no problem with the rhythm of the heart.

These ECG results require attention

As mentioned earlier, the electrical signal of the heart itself is very complex, and it is difficult for some non cardiac doctors to thoroughly understand. If there is any doubt about the results of the electrocardiogram, the most reliable way is to seek a physician in the department of cardiology to interpret the report.

Generally speaking, the words "sinus rhythm" and "mild sinus arrhythmia" mean a relatively normal electrocardiogram.

When there are results such as "conduction block", "myocardial infarction", "tachycardia", and "bradycardia", it is important to pay attention and promptly seek medical advice from the cardiology department. When the condition is severe, external symptoms usually appear. Patients or family members should remember to actively communicate with the doctor and cooperate with the treatment.

There is a heart problem, must the electrocardiogram be abnormal?

Some friends have this experience, and their heart is not comfortable. The doctor asked them to have an electrocardiogram, and the result is that the electrocardiogram shows normal.

Why is this?

Electrocardiogram is a tool for analyzing the electrical activity of the heart, which can only reflect one aspect of the heart. A metaphor circulating among doctors vividly explains the role of various heart tests.

Think of the heart as a house, then:

Heart color Doppler ultrasound, see how many rooms and halls the house is, and whether the walls of the house are still good;

Electrocardiogram to see if the circuit is normal;

Coronary angiography to see if the water pipes in the house are blocked or leaking.

Only when there is a problem with the "circuit" of the heart can there be an abnormality in the electrocardiogram.

There may be several reasons when you feel uncomfortable with your heart but your electrocardiogram shows normal.

The "cunning" of the disease was not caught

The electrocardiogram reflects the "electrification" of the heart at the time, while some arrhythmia attacks occur in bursts. At the moment of the examination, there was no abnormal rhythm, and the electrocardiogram showed no abnormalities.

At this time, the doctor may suggest that the patient take a "24-hour electrocardiogram". Keep watching for 24 hours and try to record the anomalies.

2. It's not a heart problem

"Heart discomfort" is a subjective feeling that may or may not be due to heart problems, temporary emotional stress, lung problems, stomach problems, etc.

"You know, sometimes for patients who go to the digestive department for" stomach pain, "the doctor may also ask for an electrocardiogram to rule out heart problems.".

3. The lesion is too light or too severe

"When the heart abnormality is very slight, the electrocardiogram cannot be recognized, and it may need to be judged in conjunction with other tests.".

Sometimes, too serious a heart disease can lead to "false normality" in the electrocardiogram, which is related to the principle of the electrocardiogram. The doctor will conduct ultrasound, chest radiographs, and other cardiac examinations based on the patient's condition to make a comprehensive judgment.

Through the introduction, do you have a deeper understanding of the electrocardiogram as a physical examination item?
