Holter Heart Recording
What is Holter Heart recording?
A Holter heart recording is a continuous, non-invasive test that monitors the electrical activity of your heart using a portable device called a Holter monitor. This device is worn for 24 to 48 hours or longer, depending on your doctor’s recommendation, to detect irregular heart rhythms or other cardiac abnormalities that may not be captured during a standard ECG (electrocardiogram) done in a doctor’s office.

When is it Required?
A Holter monitor is typically prescribed when:
- Symptoms are present that suggest an irregular heart rhythm or other cardiac issues, such as:
- Palpitations (feeling like your heart is racing or fluttering)
- Dizziness or lightheadedness
- Fainting (syncope)
- Unexplained fatigue
- Shortness of breath or chest discomfort
- Diagnosing arrhythmias: If a standard ECG did not capture any abnormalities, but symptoms persist.
- Monitoring after a heart event: Following a heart attack or after starting a new medication to evaluate its effects on your heart.
- Assessing pacemaker function: To ensure it is working properly and that no abnormal rhythms are occurring.
- Evaluating heart health during stress or sleep: Some irregularities only occur during specific activities or at rest.
Why is it Important?
A Holter monitor helps doctors:
- Identify and diagnose intermittent arrhythmias that may be missed in a shorter ECG.
- Assess how your heart reacts to daily activities, stress, or medications.
- Detect any early warning signs of cardiac conditions that could lead to more serious issues, such as atrial fibrillation or ventricular tachycardia.
- Guide treatment decisions and adjust medications or therapies.
How is it Used?
Angiography is crucial for diagnosing and treating various cardiovascular conditions. Here’s why it is often required:
- Electrodes (small adhesive patches) are placed on your chest, and wires connect them to a small recording device.
- You are asked to continue your normal daily activities while wearing it.
- You may need to keep a diary to record symptoms and activities during the monitoring period.
- The data collected is reviewed by your doctor to provide a detailed analysis of your heart’s function over time.
