Electrocardiogram (EKG)

The electrocardiogram is a device capable of recording the electrical activity of the heart from electrodes placed on the skin in specific locations.

Physicians use this information to discover such things as:
  • heart rate.
  • arrhythmias.
  • myocardial infarctions.
  • atrial enlargements.
