Private Holter Monitor
Ambulatory ECG
Extended heart rhythm monitoring designed to capture intermittent palpitations, arrhythmias, dizziness, blackouts, and other cardiac symptoms that a standard ECG may miss.
Choose from 24-hour, 72-hour, or 7-day Holter monitoring, with expert cardiologist analysis, clear reporting, and direct private access without a GP referral.
Holter monitoring overview
When a standard ECG isn’t enough
A standard ECG captures only a few seconds of your heart rhythm. Many important rhythm disturbances are intermittent, which means they may not appear during a short clinic test.
Holter monitoring solves this by recording your heart activity continuously while you go about normal daily life, helping identify patterns and correlate symptoms with ECG findings.
- Continuous ambulatory ECG monitoring
- Useful for palpitations, dizziness, and blackouts
- Captures intermittent rhythm disturbances
- Available as 24-hour, 72-hour, or 7-day monitoring
How Holter monitoring solves the problem
Extended ECG monitoring helps uncover rhythm problems, symptom triggers, treatment response, and intermittent events that standard testing may miss.
Capture intermittent events
Monitor over longer periods to increase the chance of recording palpitations, arrhythmias, or symptom episodes when they actually happen.
Identify rhythm patterns
See how daily life, exercise, sleep, or stress may relate to your heart rhythm and symptom profile.
Assess treatment effectiveness
Useful for checking whether anti-arrhythmic medication or other treatment is working as intended.
Support faster private diagnosis
Direct access helps reduce delay and provides consultant-reviewed reporting to guide next steps more clearly.
