They are put under your skin during minor surgery that's often done in a doctor's office. These are called implantable event monitors. Event monitors that are inserted under the skin of your chest.Others must be returned so a provider can examine the recorded information. Some of them wirelessly transmit information about your heart to a provider. These event monitors may be used for weeks to months. If you have symptoms, you hold the monitor to your chest. You wear some monitors on your chest or wrist.

Each time your heart beats, an electrical signal travels through your heart. An electrocardiogram (EKG) test is a simple, painless, and quick test that records your heart's electrical activity. ![]()
