Overview Of An Electrocardiogram

Types Of Electrocardiograms

Most patients receive the resting 12-lead electrocardiogram. This test checks their heart for abnormalities while they sit still. As mentioned, the stress test measures electrical activity in the patient's heart while they are exercising. In most cases, patients walk or run on a treadmill with electrodes on their chest. Some patients need a cardiopulmonary exercise test, which is an advanced version of the stress test! This type tests their heart, muscles, and lungs at the same time. Patients need a mouthpiece as well as the electrodes for this type.

Some patients will use a Holter monitor. They must wear this device for twenty-four to forty-eight hours. It monitors their heart through the same electrodes during this period! Another type of electrocardiogram is a signal-averaged one. It is used in combination with other types. This one is more sensitive at detecting heart issues. It takes five to twenty minutes to administer!
