What an Electrocardiogram Records
Captions available
The idea
An electrocardiogram, or ECG, records the heart's electrical activity through electrodes placed on the skin.
In practice
The electrodes pick up the small electrical changes of the heart muscle and print them on special graph paper or show them on a monitor.
Where people slip
Recording the tracing can be your task; interpreting it belongs to the provider.
