Holter Monitor
A Holter monitor is a small, portable device used to monitor and record a person’s heart activity (ECG) for an extended period of time, typically 24 to 48 hours. It is a non-invasive diagnostic tool that is used to help diagnose heart rhythm abnormalities, such as arrhythmias, or to evaluate the effectiveness of heart medications or treatments.
The Holter monitor is attached to the patient’s chest with electrodes or patches, which are connected to a small recording device that the patient wears around their waist or over their shoulder. The monitor records the electrical activity of the heart continuously, usually for a day or two, while the patient goes about their daily activities. Most Holter monitors have a button that would allow you to mark the times you are getting symptoms.
After the monitoring period, the device is returned to the healthcare provider, who downloads and analyzes the recorded data. The data is then used to identify any abnormal heart rhythms or other cardiac events that occurred during the monitoring period.
The Holter monitor is a safe and non-invasive diagnostic tool, but it may be uncomfortable to wear for some people. There are various types of Holter monitors allowing your doctor to choose the right one to suit your needs and comfort. Patients should follow any instructions provided by their healthcare provider, such as avoiding showering or swimming during the monitoring period, to ensure accurate results.
