An electrocardiogram, also called an EKG or ECG, is a simple test that detects and records the electrical activity of the heart. It is used to detect and locate the source of heart problems.
Electrical signals in the heart trigger heartbeats. These signals start at the top of the heart in an area called the right atrium.

The following is a basic primer in interpretation of the ECG (EKG). It is intended solely for teaching purposes, and should not be relied upon in clinical decision making.
ECGs can be very confusing, and there are dozens of different methods of interpretation. It's perhaps best if everyone works out their own individual approach, but here's just one approach you can build upon:

In an ECG test, the electrical impulses made while the heart is beating are recorded and usually shown on a piece of paper. This is known as an electrocardiogram, and records any problems with the heart's rhythm, and the conduction of the heart beat through the heart which may be affected by underlying heart disease. ... |

An electrocardiogram (ECG/EKG) is a test that records the electrical activity of the heart.ECG is 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 used to regulate the heart (such as a pacemaker). See also stress test and Holter monitor...

As the heart undergoes depolarization and repolarization, the electrical currents that are generated spread not only within the heart, but also throughout the body. This electrical activity generated by the heart can be measured by an array of electrodes placed on the body surface. The recorded tracing is called an electrocardiogram (ECG, or EKG). A "typical" ECG tracing ist...

In some circumstances, medical illnesses elsewhere in the body or various drugs (especially in overdose situations) affect an otherwise healthy heart in ways revealed by diagnostic or suggestive changes in to the ECG/EKG changes.In addition to the 12-lead ECG/EKG, an additional "rhythm strip" may be taken. This represents only one...

If you are having symptoms, the ECG/EKG is just one test your health care provider will use in making an overall evaluation. Your ECG may be completely normal despite the presence of significant heart disease. Here's an example: An overweight man who smokes, never exercises, and eats a fatty diet has his coronary arteries 70% blocked by cholesterol deposits...

Interpretation of an ECG/EKG is no simple matter. There are hundreds of patterns to recognize. It may be impossible to tell how long an abnormality has been present.This issue becomes crucial in an emergency situation when a person has symptoms consistent with a heart problem and an abnormal ECG/EKG..
