Holter Monitoring

Non Invasive Cardiology

Holter Monitoring is a continuous heart rhythm recording test that tracks the electrical activity of the heart over an extended period, usually 24 to 48 hours or longer if required. Unlike a standard ECG that records heart activity for only a few seconds, Holter monitoring captures heart rhythms during daily activities, sleep, exercise, and emotional stress. This test is extremely useful for detecting intermittent heart rhythm abnormalities that may not appear during routine ECG testing. It helps doctors evaluate unexplained symptoms and assess the effectiveness of ongoing cardiac treatment.

Holter monitoring plays a crucial role in diagnosing arrhythmias, palpitations, unexplained fainting, dizziness, or episodes of rapid or slow heartbeats. It is also used to assess pacemaker function and monitor heart rhythm after cardiac procedures or medication changes.

Why Is Holter Monitoring Done?

• Frequent palpitations or irregular heartbeat

• Unexplained dizziness or fainting episodes

• Suspected arrhythmias

• Evaluation after pacemaker implantation

• Monitoring response to heart medications

Procedure

Small electrodes are placed on the chest and connected to a portable recording device worn on a belt or shoulder strap. The patient is advised to continue normal daily activities while avoiding water exposure. The device records heart activity continuously throughout the monitoring period. Patients may be asked to maintain a diary noting symptoms and activities to correlate with heart rhythm changes. After completion, the device is removed and data is analyzed by the cardiologist.
