Heart Health Test
24-Hour ECG Monitor (Holter Monitor)
Continuous Heart Rhythm Monitoring
A 24-hour ECG monitor (Holter monitor) continuously records your heart's electrical activity over an extended period, helping detect intermittent rhythm abnormalities that may not be captured during a standard ECG.
Visit our Wigmore Street clinic where we will fit you with this portable device. Wear it for 24 hours while you go about your normal daily activities, providing a comprehensive view of your heart's rhythm throughout the day and night. Return to the clinic after 24 hours to have the device removed and results analyzed.
The test is particularly useful for detecting arrhythmias that come and go, and for assessing symptoms like palpitations, dizziness, or chest pain.
What Is It?
A 24-hour ECG monitor, also known as a Holter monitor, is a portable device that continuously tracks your heart's electrical activity throughout an entire day and night. Unlike a standard ECG which only captures a few seconds, this test records every heartbeat over 24 hours while you go about your normal activities—working, eating, sleeping, and exercising. This extended monitoring helps detect heart rhythm problems that may be intermittent and not present during a brief clinic visit.
Why It's Important
Many heart rhythm irregularities don't occur constantly—they come and go throughout the day, often triggered by specific activities, stress, or sleep. If you experience symptoms like palpitations, dizziness, chest discomfort, or unexplained fatigue that aren't present during a regular ECG, a 24-hour monitor can capture what's actually happening when symptoms occur. This test is crucial for diagnosing intermittent arrhythmias, assessing how your heart responds to daily activities, and determining if concerning symptoms are related to your heart rhythm. It provides the comprehensive picture needed to identify problems that might be missed in a standard ECG.
