A graphic record of the electrical activity and heart beat pattern.
Tracing that provides a graphic illustration of the electrical current generated by excitation of the heart muscle.
A test to record the electrical processes originating within the heart, such as heartbeat, and to assess heart problems. The test involves electrodes, or leads, attached to the chest, neck, arms, and legs.
A record of the electrical activity of the heart.
A graphic display of the electrical activity of the heart, recorded from electrodes on the chest and extremities.
A tracing representing the heart’s electrical action that is traced by amplifying the minutely small electrical impulses generated by the heart.
A chart which records the electrical impulses in the heart muscle.
A record of the electrical activity of the heart that provides information about cardiac rhythm and function.
Record of the electrical forces producing heart contractions.
A record of the heart’s electrical activity and impulses via monitoring equipment and a printout; important in diagnosing abnormal heart rhythms.
A recording of the electrical activity of the heart as a graph or series of waves on a strip of paper; commonly abbreviated ECG.
A recording of the electrical activity of the heart on a moving paper strip. The ECG tracing is recorded by means of an apparatus called an electrocardiograph. It aids in the diagnosis of heart disease, which may produce characteristic changes in the ECG.
The recording made in the diagnostic procedure called electrocardiography. “EKG” is used interchangeably with “ECG” as an abbreviation.
A record of the electrical activity of the heart, consisting of waves called P, Q, R, S, T, and sometimes U. The first, or P, wave is caused by the depolarization of the atria, whose electrical changes in turn cause atrial contraction. The Q, R, and S waves (QRS complex) correspond to depolarization of ventricular muscle. The T wave corresponds to ventricular repolarization. The electrocardiogram gives important information concerning the spread of electricity to the different parts of the heart and is used to diagnose rhythm and conduction disturbances, myocardial infarction or ischemia, chamber enlargement, and metabolic disorders, among others.
The diagnostic procedure employed to assess the electrical signals originating from the cardiac muscle, with the purpose of obtaining valuable insights into the intricacies of its anatomical composition or physiological behavior.
The visual depiction of the brief electrical waves generated during the heart muscle’s contraction offers crucial insights to cardiologists, enabling them to discern the specific type and characteristics of the prevailing cardiac disorder. This is commonly abbreviated as E.C.G.
