Holter and event monitors are medical devices that record the heart's electrical activity. Doctors most often use these monitors to diagnose arrhythmias. These are problems with the speed or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or irregularly.
These monitors also can check whether treatments for arrhythmias are working or perhaps changes need to be made to your medications. Remember you are an individual unique from your husband and the medications and treatment will most likely be different for each of you.
Next time you visit your Dr. do feel comfortable in asking the Dr. questions as patients have the right to know about their dx and treatment plan.
