Who / What
Electrocardiography is the process of examining the heart's electrical activity using a device called an electrocardiograph. This process produces an electrocardiogram (ECG or EKG), which is a graph displaying the heart's electrical activity throughout each cardiac cycle. It involves recording the voltage changes caused by the depolarization and repolarization of the heart muscle.
