Holter ECG is an effective diagnostic method that allows you to monitor heart activity around the clock.
It is an extremely useful tool in diagnosing various heart diseases and assessing the effectiveness of treatment. In this article we will discuss the Holter ECG test, its indications, contraindications, interpretation of the results and tips on how to sleep with a Holter on your body.
What is the purpose of a Holter ECG test?
A Holter ECG test, also known as ambulatory electrocardiography, is performed to monitor a patient’s heart rate for a specific period of time, usually 24 hours. The main objectives of this study are:
- Diagnosis of heart rhythm disorders such as atrial fibrillation or extrasystole.
- Monitoring the effectiveness of treatment for heart diseases, such as hypertension or coronary artery disease.
- Identification of episodes of pain or shortness of breath related to cardiac activity.
- Assessment of the heart’s response to specific stressors, such as physical exercise or emotions.
What can a Holter ECG show?
A Holter ECG test can provide valuable information about the functioning of a patient’s heart. The results of this study may reveal:
- Episodes of irregular heart rhythm.
- Decreases or increases in heart rate.
- Pauses in heartbeat that may suggest conduction blocks.
- Cardiac hypoxia episodes.
- Effectiveness of pharmacological or surgical treatment.
Holter ECG – contraindications to performing the test
Although the Holter ECG test is relatively safe and non-invasive, there are some contraindications that may prevent it from being performed. This test should be avoided if:
- Allergy or hypersensitivity to electrodes or wristbands.
- Damaged or injured skin where the electrodes are placed.
- Patients with skin diseases such as eczema or psoriasis in the area where the electrodes will be attached.
- Patients with difficulty understanding and following instructions related to examination behavior.
What does a Holter ECG test look like and how long does it take? how to sleep with a holter monitor?
Preparing for a Holter ECG test is relatively simple. Electrodes are attached to the patient’s chest, which are connected to a small, portable device that records the heart rate. This device is usually worn on a belt or in a special bag for a period of 24 hours.
During the examination, the patient should lead a normal lifestyle and keep a diary of activity and possible symptoms. It is important not to remove the device and electrodes throughout the test, even while sleeping. How to sleep with Holter? Here are some tips:
- Avoid excessive twisting of cables and do not squeeze the device while sleeping.
- Try to sleep on your back or side to avoid pressure on the electrodes on your chest.
- If you experience discomfort while sleeping or the electrodes begin to come off, consult your healthcare professional.
Holter ECG – interpretation of heart function test results
Interpreting Holter ECG results is the task of a doctor specializing in cardiology. The doctor analyzes the recorded data, taking into account heart activity in various situations, such as sleep, physical exercise, stress or peace. Based on these results, it can accurately assess the risk of cardiac arrhythmias, myocardial ischemia and the effectiveness of treatment.
What is the difference between an ECG Holter and a Pressure Holter?
ECG Holter and Blood Pressure Holter are two different tests, although both monitor heart function. An ECG Holter focuses on recording the heart’s electrical activity, while a Blood Pressure Holter measures blood pressure around the clock. Both tests are used to diagnose and monitor heart disease, but they focus on different aspects of heart function.
Your suggestions
It is always worth consulting a cardiologist before the examination and following his recommendations regarding the preparation and wearing of an ECG Holter. Remember that the accuracy of the results also depends on carefully keeping a diary of your activity and any symptoms you may have during the test.
