Have you noticed the signs of "heart palpitations"? There are 4 heart conditions that may not be detected by routine examinations →

Put it in the past

My heart suddenly started beating fast and I felt panicky.

That's called an unexpected heartbeat

But now

996 and staying up late

If the heart suddenly hits

I just feel like I'm finished.

For peace of mind

You decided to go to the hospital.

Finally, on the way... eh? Okay?

Arrived at the hospital

The electrocardiogram showed nothing.

At this time, the doctor may recommend you

Do a 24-hour dynamic electrocardiogram

The dynamic electrocardiogram, referred to as DCG, is a portable ECG monitoring device that patients generally need to wear on their bodies for about 24 hours, commonly known as a "back box".

So in what circumstances should a dynamic electrocardiogram be used?

Symptoms such as palpitations, chest tightness, and chest pain are sometimes caused by paroxysmal heart attacks, and a routine electrocardiogram may show no abnormalities.

At this time, dynamic electrocardiogram comes in handy.

It can help capture occasional, short-term ECG abnormalities and provide doctors with effective diagnostic basis.

In the daily life of the subject, the dynamic electrocardiogram recorder continuously records the entire process of cardiac electrical activity for 24 hours , capturing the changes in the heart's electrical activity when it is active or at rest.

If you really have any heart problems, you basically cannot escape this 24-hour "heart monitoring".

During routine checkups, doctors generally won't force you to do a dynamic electrocardiogram.

However, if you are in the following situations, a dynamic electrocardiogram must be done:

Suspected arrhythmia: Dynamic electrocardiogram can capture short-term abnormal ECG changes and understand the origin, duration, frequency, occurrence and termination patterns of arrhythmia.

Screening for myocardial ischemia: For high-risk groups such as those with a family history of coronary heart disease, long-term smoking, and hypertension, dynamic electrocardiogram can help detect myocardial ischemia.

Evaluation of the efficacy of antiarrhythmic drugs: Holter is a reliable clinical indicator for studying and evaluating the efficacy of antiarrhythmic drugs.

Assessing pacemaker function: For patients with pacemakers installed, dynamic electrocardiogram can more accurately assess their working condition.

It can proceed normally.

Many people mistakenly believe that it is best to move less after wearing this device, but this concept is actually inaccurate.

Guess why it is called "Dynamic Electrocardiogram"?

Of course, the wearer is required to carry out activities according to his normal work and lifestyle , and behave as he usually does.

The information collected in this way can more truly reflect the heart condition in daily life , thereby providing a more accurate basis for diagnosis.

24 hours is not a fixed standard!

During routine physical examinations, it is generally required to wear it for 24 hours.

But in fact, as long as the device successfully captures abnormal or uncomfortable ECG changes, it is effective even if it is worn for less than 24 hours.

Especially for those patients who already have heart disease, in order to improve the accuracy of diagnosis, doctors may recommend appropriately extending the testing time, which will help detect potential disease conditions more accurately.

Before wearing the recorder

1. It is best to take a shower before wearing it. If you have a lot of chest hair, you need to shave it.

2. Wear loose and comfortable clothing . Ladies should avoid wearing dresses.

3. If you take any specific medications (such as digitalis, potassium salts, or antiarrhythmic drugs), you must inform your doctor or nurse in advance.

After wearing the recorder

1. Avoid strenuous exercise and exposure to strong magnetic fields.

2. Try not to take a bath during wearing and keep your skin dry.

3. Avoid excessive sweating. If the electrode falls off, ensure that it is in the correct position and can be put back in place.

4. If any discomfort symptoms occur during the monitoring process, the time and conditions of occurrence should be recorded in time for the doctor to analyze and diagnose.

5. If allergic symptoms such as local redness, itching, etc. occur on the skin around the patch, contact medical personnel immediately.

To sum up, I believe everyone has a comprehensive understanding of the dynamic electrocardiogram.

If you are worried that there is something wrong with your heart, you can add this item to the check-up.
