What is Electrocardiogram? (The meaning and diagram)
An electrocardiogram (ECG or EKG) is a test that checks for problems with the electrical activity of your heart. An EKG machine translates the heart’s electrical activity into line tracings on paper. The spikes and dips in the line tracings are called waves. For more on this, go here: Electrocardiogram Definition
Each beat of your heart is triggered by an electrical impulse normally generated from special cells in the upper right chamber of your heart. An electrocardiogram — also called an ECG or EKG — records these electrical signals as they travel through your heart. Your doctor can use an electrocardiogram to look for patterns among these heartbeats and rhythms to diagnose various heart conditions.
The electrocardiogram (ECG) is a device used to record on graph paper the electrical activity of the heart. The picture is drawn by a computer from information supplied by the electrodes. The following diagram illustrates how ECG is used to monitor the electrical activity of a patient’s heart.
What is the purpose of using an Electrocardiogram?
- To access your heart rhythm
- To diagnose poor blood flow to the heart muscle (ischemia)
- To diagnose a heart attack
- To diagnose abnormalities of your heart, such as: heart chamber enlargement, abnormal electrical conduction
