Long-term ECG

A long-term ECG, also known as a Holter monitor, is a diagnostic tool that continuously records the electrical activity of the heart over a longer period, typically 24 to 48 hours. You wear a small, portable device that records heart rhythms to identify arrhythmias or other irregular heart activities that may not be detected during a normal ECG.

What is a long-term ECG and what is it used for?

A long-term ECG is a diagnostic method in which the electrical activity of the heart is recorded over a longer period (typically 24 hours or longer). It is used to detect heart rhythm disorders or other heart problems that may not be detected during a short ECG examination.

How is a long-term ECG performed?

A long-term ECG is performed with a portable device that is connected to the patient. Electrodes are attached to the patient’s chest and connected to the recording device. The patient wears the device for a certain period, during which it continuously records the heart activity. After the recording, the device is evaluated and interpreted by a doctor.

What are the advantages of a long-term ECG compared to a standard ECG?

A long-term ECG allows the detection of heart rhythm disorders that may not occur during a standard ECG. It also offers the possibility to monitor the heart over a longer period, which can be helpful to detect intermittent problems that may not be visible during a short ECG.

Are there any limitations or risks associated with a long-term ECG?

Generally, a long-term ECG is a safe and non-invasive examination. However, there are some limitations and potential risks. For example, some patients may experience skin irritation from the electrodes, and wearing the recording device may be uncomfortable. In addition, the recording of artifacts or false readings due to patient movement may occur.

How is the result of a long-term ECG interpreted?

The result of a long-term ECG is interpreted by a cardiologist who specializes in the analysis of heart rhythm disorders. The cardiologist reviews the recorded data and looks for signs of arrhythmias, heart blockages, or other abnormalities. Based on these findings, the doctor can make recommendations for treatment or further diagnostic tests.
