What is an Electrocardiogram?

An electrocardiogram is a tracing of your heart’s rhythm. With each heartbeat electricity passes through your heart causing it to pump. An EKG is a recording of the electrical activity.

Ten electrodes or sticky patches are placed on your chest and are attached to the EKG machine by long wires. The test takes only seconds to complete and is painless.

An electrocardiogram gives us a lot of information about your heart rhythm.

  •   How fast your heart is beating
  •   Whether the rhythm of your heartbeat is steady or irregular
  •   The strength and timing of electrical signals as they pass through each part of your heart

This test is used to detect and evaluate many heart problems, such as heart attack and arrhythmias. EKG results also can suggest other disorders that affect heart function.
