Electrocardiogram

What is an Electrocardiogram ?

An electrocardiogram is a simple, painless test that records the heart's electrical activity.

It is a low-cost, noninvasive, and effective test for arrhythmia analysis and has become the standard diagnostic tool.

With each heartbeat, an electrical signal spreads from the top of the heart to the bottom. As it travels, the signal causes the heart to contract and pump blood.

Other names for ECG?

An electrocardiogram also called an EKG or ECG.

Sometimes the ECG test is called a 12-lead EKG or 12-lead ECG,this is because the heart's electrical activity most often is recorded from 12 different places on the body at the same time.

What an ECG Shows?

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

How ECG is useful?

Doctors use ECGs to detect and study many heart problems, such as heart attacks, arrhythmias (ah-RITH-me-ahs), and heart failure.

An EKG translates the heart's electrical activity into line tracings on paper.

The test measures how electrical impulses move through the heart muscle as it contracts and relaxes.
