A Holter Monitor is a small portable device that you wear under your clothing to measure and record your heart activity (EKG). It records your heart rate and rhythm.
A Holter Monitor is used to either evaluate symptoms of palpitations or to determine the nature, extent, and severity of any known underlying cardiac arrhythmias or conduction abnormalities. The results of the Holter Monitor can help exclude or establish the presence of cardiac arrhythmias and/or conduction abnormalities and help guide further treatment as indicated.
Typically, a Holter Monitor is worn for 24 hours. However, there are small portable devices that can be worn continuously for much longer in duration. These are devices that can be put on and taken off by the patient intermittently during the course of monitoring. There are also devices that can be worn continually and would allow. you to exercise, play sports and even shower with them in place. It all depends on the nature of your symptoms and/or diagnoses. The cardiologist will help determine what would be most appropriate in your specific situation.
