Electrocardiography (C1623258) | |
|---|---|
| Definition (MSH) | Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY. |
| Definition (CSP) | measurement and interpretation of electrical manifestations of heart activity. |
| Definition (NCI) | A procedure which records the electrical current in the heart in the form of a continuous strip graph. The electrocardiography results may determine whether the heart is performing normally or suffering from abnormalities, may indicate coronary artery blockages, can be used for detecting calcium, magnesium and other electrolyte disturbances, allow the detection of conduction abnormalities, indicate the physical shape of a patient during stress test and provide information on the physical condition of the heart. |
