The electrocardiogram (EKG) is a fundamental diagnostic tool that records the electrical activity of the heart. It provides valuable information about the heart rhythm, heart rate, and potential circulatory disturbances in the heart muscle.

During the examination, electrodes are attached to the skin, which detect the heart’s electrical impulses. These impulses are displayed as waves on a monitor or paper. The EKG is commonly used to diagnose heart rhythm disorders, heart attacks, or other heart conditions.

The examination is quick, painless, and straightforward. The patient lies relaxed on a table during the recording. An EKG typically takes only a few minutes and can be performed both in a practice setting and in a hospital.

The EKG is used in various forms:

• Resting EKG: Recording of heart activity in a resting state.
• Exercise EKG: Recording of heart rhythm during physical activity.
• Holter EKG: Continuous recording over 24 hours or more to detect sporadic heart rhythm disorders.

Overall, the EKG is an important tool for monitoring heart health, early detection of heart problems, and initiating targeted treatments.
