Electrocardiography

 

Electrocardiography


Electrocardiography commonly referred to as an ECG or EKG is used to measure the heart’s electrical conduction system. It picks up electrical impulses generated by the polarization and depolarization of cardiac tissue and translates into a waveform. The waveform is then used to measure the rate and regularity of heartbeats, as well as the size and position of the chambers, the presence of any damage to the heart, and the effects of drugs or devices (such as a pacemaker) used to regulate the heart.
