Electrocardiogram The ECG is a graphic display of the electrical activity of the heart, which is analyzed by time intervals and segments. Continuous tracing of the cardiac cycle activity is captured as heart cells are electrically stimulated, causing depolarization and movement of the activity through the cells of the myocardium.

electrocardiography Definition. 1  Electrocardiography is a commonly used, noninvasive procedure for recording electrical changes in the heart. The record, which is called an electrocardiogram (ECG or EKG), shows the series of waves that relate to the electrical impulses which occur during each beat of the heart. The results are printed on paper or displayed on a monitor. The waves in a normal record are named P, Q, R, S, and T and follow in alphabetical order.

Heart Disease, Electrocardiogram, and Specialized EKGs An electrocardiogram (also called EKG or ECG) is a test that records the electrical activity of your heart through small electrode patches attached to the skin of your chest, arms, and legs. An EKG may be part of a routine physical exam or it may be used as a test for heart disease. An EKG can be used to further investigate symptoms related to heart problems. EKGs are quick, safe, painless, and inexpensive tests that are routinely performed if a heart condition is suspected.

- An electrocardiogram (ECG or EKG), is a measurement of the electrical activity of the heart. By placing electrodes at specific locations on the body (chest, arms, and legs), a graphic representation, or tracing, of the electrical activity can be obtained.n ECG is one of the simplest and fastest procedures used to evaluate the heart. An ECG technician, nurse, or physician typically will place 12 separate electrodes (small plastic patches) at specific locations on your chest, arms, and legs.

Electrocardiogram (ECG): Definition & Wave Types An ECG is performed by placing electrodes on the skin overlying the heart. As the electrical impulse moves from the atria, which are the top two chambers, to the ventricles down below, the voltage measurement between the electrodes varies, and this produces a graph of how your heart is performing.

Overview An ECG is a noninvasive, painless test with quick results. During an ECG, sensors (electrodes) that can detect the electrical activity of your heart are attached to your chest and sometimes your limbs. These sensors are usually left on for just a few minutes. Your doctor may discuss your results with you the same day as your electrocardiogram or at your next appointment.

Electrocardiogram (ECG or EKG) What is an electrocardiogram (ECG, EKG)? The electrocardiogram (ECG or EKG) is a noninvasive test that is used to reflect underlying heart conditions by measuring the electrical activity of the heart. By positioning leads (electrical sensing devices) on the body in standardized locations, information about many heart conditions can be learned by looking for characteristic patterns on the EKG.
