Electrocardiogram
Electrocardiogram (ECG/EKG)
An electrocardiogram (ECG or EKG) is a record of the electrical activity of a person's heart. It is used to diagnose heart conditions and check the person's heart health. An ECG is one of the most common tests for diagnosing irregular heart conditions and heart diseases and monitoring the health of a person.
Preparation for an Electrocardiogram
Before having an ECG, it is important to inform your doctor about any antibiotics, medications, and supplements you are taking.

The patient is then asked to remain still while the ECG machine records the electrical activity of the heart. The whole procedure takes hardly 10 minutes.
