diagnostic procedure consisting of recording the activity of the heart electronically with a cardiograph (and producing a cardiogram)
provides a graphic recording of the heart’s electrical activity
An EKG records the electrical activity of the heart. "Leads" (wires) are placed on the chest and the extremities.
A device used for recording the electrical activity of the myocardium to detect transmission of the cardiac impulse through the conductive tissues of the muscle for the diagnosis of specific cardiac abnormalities.
a method of recording the electrical activity of the heart.
Procedure used to measure the electrical activity of the heart muscle. It provides information about how the heart functions. The record produced by ECG is known as an electrocardiogram.
A tracing showing the changes in electric potential produced by the contractions of the heart.
A diagnostic procedure that records the electrical activity of the heart muscle.
( ECG)—A method of recording the electrical currents that pass through the heart muscle during each heartbeat. To record a typical ECG, electrodes are attached to the arms and legs, and the electrical pulses are recorded as the patient relaxes on an examining table. The Holter monitor, a portable device, takes a continuous ECG during an extended period and provides physicians with information about a patient's heart rhythm during a full day of normal activity to aid in detecting rhythm disturbances. Newer devices allow patients to activate a portable recorder whenever they suspect an abnormal heart rhythm. This test is also referred to as an EKG because the procedure was developed in the Netherlands and was first called an "electrokardiogram."
Method of measuring the electrical activity of the heart. EKG is continuously recorded in both diagnostic sleep studies and CPAP titration sleep studies.
