Holter monitoring

Holter monitoring is a non-invasive medical test that records the heart’s rhythm over a 24- to 48-hour period. It’s a portable device that’s worn like a vest or attached to a belt, with electrodes placed on the chest to capture the heart’s electrical activity.

The test is used to:

1. Diagnose arrhythmias (abnormal heart rhythms)
2. Identify palpitations or skipped beats
3. Monitor the effectiveness of heart medications
4. Detect silent ischemia (heart damage without symptoms)
5. Evaluate chest pain or dizziness

The Holter monitor records the heart’s rhythm continuously, providing valuable information on:

1. Heart rate and rhythm
2. Atrial and ventricular activity
3. Abnormal heartbeats or pauses
4. Heart rate variability

The test is usually performed in a healthcare setting, and the data is analyzed by a cardiologist or healthcare professional to diagnose and manage heart conditions.

Note: Holter monitoring is also known as ambulatory electrocardiography (AECG) or 24-hour electrocardiography.
