An ECG (also called EKG or Electrocardiogram ) measures the heart's electrical activity. This can help doctors tell how the heart is working and identify any problems.
The ECG can help show the rate and regularity of heartbeats, the size and position of the heart's chambers, and whether there is any damage.
An EKG records the heart's activity through small wires taped to your body.
