24-hour Holter & 24/7 Ambulatory BP Monitoring
About the Procedure
24-hour Holter monitoring continuously records the heart’s electrical activity over a full day to detect intermittent rhythm abnormalities that may not appear during a routine ECG. Ambulatory Blood Pressure Monitoring (ABPM) measures blood pressure at regular intervals over 24 hours, including during sleep, providing a true picture of daily BP variations. Together, these tests help diagnose arrhythmias, unexplained symptoms, masked or nocturnal hypertension, and assess treatment effectiveness with greater accuracy than single readings.
Benefits
- Detects intermittent arrhythmias causing palpitations or syncope.
- Identifies masked, white-coat, or nocturnal hypertension patterns.
- Correlates symptoms with heart rhythm or BP changes.
- Guides treatment decisions and medication adjustments.
Common uses
- Evaluation of palpitations, dizziness, or unexplained fainting.
- Monitoring known arrhythmias or therapy effectiveness.
- Diagnosing hypertension patterns beyond clinic readings.
- Risk assessment for cardiovascular events.
Care / Instructions
- Continue normal daily activities during monitoring period.
- Keep a symptom and activity diary for correlation.
- Avoid getting devices wet unless instructed otherwise.
- Return equipment promptly for accurate data analysis.
