24-48-72 Hour Holter ECG Monitoring

The 24-48-72 hour Holter ECG, also known as Dynamic Electrocardiogram according to Holter, is a non-invasive diagnostic test that allows continuous monitoring of heart rhythm over a period of 24 hours or more.

This examination enables the detection of any cardiac arrhythmias. Cardiac arrhythmias are abnormalities in heart rhythm, such as too fast (tachycardia), too slow (bradycardia), or irregular (atrial fibrillation) heartbeats. It is also useful for:

Evaluating the effectiveness of antiarrhythmic medications (Holter ECG allows verification of whether the medications you are taking for cardiac arrhythmias are adequately controlling your heart rhythm).

Identifying any episodes of cardiac ischemia: Cardiac ischemia is a reduction in blood flow to the heart, which can cause symptoms such as chest pain (angina pectoris) or shortness of breath.

Studying variations in heart rhythm in different situations (such as how heart rhythm changes throughout the day and night, during physical activity, and in moments of stress).

How does the examination work?

During the examination, you will be fitted with a small device similar to a bracelet, called a Holter monitor, which automatically records your heartbeats and the electrical activity of the heart at regular intervals (usually every 1-5 seconds). The monitor is connected to adhesive electrodes that are applied to your chest.

What to do during the examination?

You will need to wear the Holter monitor for 24, 48, or 72 hours, day and night. You can perform most of your normal daily activities, but it is important to avoid bathing or showering with the monitor. You will also need to keep a diary of your activities and when you take medications.
