A recording of the electrical activity of the heart on a moving strip of paper It helps determine how well and how fast the heart is working Certain types of heart disease are associated with specific changes in the EKG recording
Measurement of the heart's electrical activity by placing electrodes on the arms, legs and chest This test helps identify abnormally enlarged heart chambers or abnormalities of the heart's electrical system (arrhythmias)
A machine that measures the electrical impulses of the heart and transfers the information gathered to a report that prints out a graph of the patient's heartbeats Used as a diagnostic tool
An electrocardiogram (ECG or EKG) is the graphic record of the heart's electrical currents obtained with the electrocardiograph, an instrument designed for recording the electrical currents that traverse the heart and initiate its contraction
A recording of the electrical activity of the heart on a moving strip of paper The electrocardiogram detects and records the electrical potential of the heart during contraction
(ECG or EKG), a measurement of the electrical activity of the heart which is obtained by attaching electrodes to the body The ECG can detect an abnormal heart rhythm or other abnormality
The electrocardiogram is a test of the way the electrical impulses flow through the heart Abnormalities may indicate that a heart attack has occurred in the past If performed during symptoms suggestive of coronary artery disease angina pectoris, abnormalities may confirm the diagnosis of ischemic heart disease
If someone has an electrocardiogram, doctors use special equipment to measure the electric currents produced by that person's heart in order to see whether it is working normally. an ECG
A recording of the electrical output of the heart It becomes abnormal only when there is advanced heart disease It cannot detect early heart disease and may even be normal during a heart attack It does not provide information about the function of the heart anymore than measuring the voltage from a car battery will reflect the performance of a car
This is a tracing over time of the electrical potential between two points on the surface of the body caused by a beating heart The electrocardiogram reflects the contractile activity of the heart muscle and can be used to identify a variety of cardiac dysfunctions including arrhythmias, infarctions, and hypertrophy Press the "back" button to return to where you came from
