Patients often experience heart rhythm disorders without realizing it. Your doctor may prescribe a heart monitor to determine if you are having an arrhythmia. Tests such as electrocardiograms (ECG) only allow a doctor to look at the heart’s activity at one point in time while a monitor can capture your heart rhythms over a longer period of time. Until you are diagnosed with an arrhythmia, you may be at risk for future symptoms. Wearing the monitor will help with the diagnosis of potential heart rhythm problems when you are outside a clinic or hospital and while you going about your daily activities. By continuously tracking your heart rhythms, doctors are more likely to discover if an arrhythmia is causing your symptoms, and then determine the appropriate treatment for your condition. The monitors can be prescribed from 24 hours to 30 days long, depending on the patients’ needs.
