Question

electrocardiogram (ecg)

Answer 1

It measures the electrical impulses of the heart, so if there is an abnormal rhythm etc, it can be detected.

Answer 2

The electrocardiogram (ECG or EKG) is a diagnostic tool that measures and records the electrical activity of the heart in exquisite detail. Interpretation of these details allows diagnosis of a wide range of heart conditions. These conditions can vary from minor to life threatening.

The term electrocardiogram was introduced by Willem Einthoven in 1893 at a meeting of the Dutch Medical Society. In 1924, Einthoven received the Nobel Prize for his life's work in developing the ECG.

The ECG has evolved over the years.

The standard 12-lead ECG that is used throughout the world was introduced in 1942.

It is called a 12-lead ECG because it examines the electrical activity of the heart from 12 points of view.

This is necessary because no single point (or even 2 or 3 points of view) provides a complete picture of what is going on.

To fully understand how an ECG reveals useful information about the condition of your heart requires a basic understanding of the anatomy (that is, the structure) and physiology (that is, the function) of the heart.
