NCIt definition : A record of the electrical activity of the heart.;
Alternative definition : ACC/AHA: The record produced by the variations in electrical potential caused by electrical
activity of the heart muscle and detected at the body surface, as a method for studying
the action of the heart muscle.; NCI-GLOSS: A line graph that shows changes in the electrical activity of the heart
over time. It is made by an instrument called an electrocardiograph. The graph can
show that there are abnormal conditions, such as blocked arteries, changes in electrolytes
(particles with electrical charges), and changes in the way electrical currents pass
through the heart tissue.; ICH: The procedures for the recordings produced by the variations in electrical potential
caused by electrical activity of the heart muscle and detected at the body surface,
as a method for studying the action of the heart muscle.;
