Cardiac rhythm disorders often occur unpredictably – at night, during exertion, or at times when the patient is not in a medical office. That’s why a standard ECG is not always enough to identify the problem. At Diagnostic Center “Heart,” we offer Holter ECG monitoring – a 24- or 48-hour recording of the heart’s electrical activity in a real-world setting, providing highly accurate and valuable information about the patient’s condition.

What is Holter ECG?

Holter ECG is a prolonged, outpatient recording of an electrocardiogram, typically over 24 or 48 hours. A small device attached to the body with electrodes continuously registers heart activity while the patient goes about their daily routine – at home, at work, during sleep, and physical activity.

The method is completely painless and extremely helpful in detecting arrhythmias, pauses, extrasystoles, asymptomatic episodes, and other rhythm disorders.

When is Holter ECG recommended?

Holter monitoring is indicated for:

• Suspected arrhythmias not captured by a standard ECG
• Sensations of heart “skipping” or irregular rhythm
• Dizziness, fatigue, or brief fainting episodes
• Unexplained fatigue or shortness of breath with minimal exertion
• Unexplained syncope (fainting)
• Nighttime awakenings with a racing heart
• Evaluating treatment effectiveness in known arrhythmias
• Preoperative assessment in patients with cardiac risk
• Follow-up after a heart attack, stroke, or myocarditis

What can Holter ECG detect?

Holter ECG helps identify:

• Cardiac arrhythmias (extrasystoles, tachycardia, bradycardia)
• Atrial fibrillation and other supraventricular rhythm disorders
• Pauses and missed heartbeats
• Sleep-related rhythm disorders
• Episodes of sudden rhythm change
• The influence of stress, activity, and sleep on the heart
• The effect and efficacy of antiarrhythmic medication

How is the Holter device applied?

The procedure includes:

1. Placing electrodes on the chest, connected to a small recording device
2. Patient instruction on how to wear the device, what to avoid, and how to keep a symptom diary
3. Normal daily routine – patients should continue their usual activities while wearing the device
4. Returning the device after 24 or 48 hours
5. Data analysis by our specialist with a final report

The test is painless and non-invasive but requires cooperation and proper device use during the recording period.
