Ambulatory cardiac monitoring is a way to watch and record the electrical activity of your heart. It is done as you go about your daily activities. Most of the recording devices are about the size of a cell phone.
This test is used to determine whether the heart may be beating too slow or too fast. It also detects any abnormalities in heart rhythm.
Your heartbeat is regulated by electrical impulses. Sometimes there are abnormalities with these impulses. When the abnormality is happening all the time, it is easy to find in the doctor's office. But sometimes the problem comes and goes. Ambulatory cardiac monitoring records your heart’s electrical activity for long periods of time. The length of time makes it much more likely to detect an abnormality that comes and goes.
Ambulatory cardiac monitoring may be advised to assess:
You will first be evaluated by a doctor. An electrocardiogram (EKG) checks the electrical activity of your heart. It will likely be done in the office.
The test steps will depend on the type of device used:
Certain environmental interferences should be avoided, including: magnets, metal detectors, high-voltage wires, radio frequency signalers, microwave ovens, electric blankets, electric toothbrushes, and electric razors.
A typical interval is 24 hours. If your problem is less frequent than that, you may need to be monitored for a longer period of time. Longer monitoring often requires different devices.
