Ambulatory ECG
Introduction
Ambulatory ECG (electrocardiogram), commonly known as Holter monitoring or continuous ECG recording, is a diagnostic tool used to monitor the heart's electrical activity over a prolonged period while a person goes about their daily activities.
Why is it Used?
Doctors use ambulatory ECG to detect intermittent cardiac abnormalities that may not appear during a short clinic ECG test. It helps in diagnosing: - Arrhythmias (irregular heartbeats) - Silent ischemia (lack of blood flow to the heart without symptoms) - Unexplained fainting or dizziness - Monitoring response to heart medication and treatments
Types of Ambulatory ECG
- Holter Monitor : Continuous ECG monitoring for 24-48 hours.
- Event Monitor : Activated by the patient when symptoms occur, used for weeks.
- Patch Monitor : A small, wireless wearable ECG that records for longer durations.
How is it Performed?
- Electrodes are placed on the chest and connected to a small recording device.
- The patient wears the monitor while engaging in normal daily activities.
- The data is later analyzed by a cardiologist.
Benefits of Ambulatory ECG
- Provides a more comprehensive assessment of heart rhythm.
- Helps detect arrhythmias that occur intermittently.
- Allows evaluation of heart activity in real-life conditions.
Patient Instructions
- Keep a symptom diary to correlate symptoms with ECG recordings.
- Avoid moisture to prevent electrode detachment.
- Continue normal activities unless advised otherwise.
Conclusion
Ambulatory ECG is a valuable tool in detecting heart rhythm disorders, providing extended monitoring beyond what a standard ECG can offer.

The heart is an organ that does not know how to "keep silent" if something goes wrong. Chest pain, shortness of breath, swelling, dizziness, and rhythm disturbances are the symptoms that require our attention. The best prevention of heart disease is careful attention to your health, regular checkups with a doctor, and a healthy lifestyle. Take care of your heart, and it will serve you for many years!
