What is it? An electrocardiogram — abbreviated as EKG or ECG — is a test that measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or “wave”) travels through the heart. This wave causes the muscle to squeeze and pump blood from the heart.

An electrocardiogram can provide considerable information about the health and functioning of your heart. Your doctor can learn about your heart rhythm, the chambers of your heart, the functioning of your heart muscle, whether the heart is enlarged or thickened, and whether you had a heart attack in the past.

What is an electrocardiogram? An electrocardiogram (ECG) is one of the simplest and fastest tests used to evaluate the heart. Electrodes (small, plastic patches that stick to the skin) are placed at certain spots on the chest, arms, and legs. The electrodes are connected to an ECG machine by lead wires.

Heart attack. An ECG can show evidence of a previous heart attack or one that's in progress. The patterns on the ECG may indicate which part of your heart has been damaged, as well as the extent of the damage. Inadequate blood and oxygen supply to the heart.

Electrocardiogram (ECG) The electrocardiogram is commonly used to detect abnormal heart rhythms and to investigate the cause of chest pains. Note: the information below is a general guide only. The arrangements, and the way tests are performed, may vary between different hospitals.

Heart rate. Normally, heart rate can be measured by checking your pulse. An ECG may be helpful if your pulse is difficult to feel or too fast or too irregular to count accurately. An ECG can help your doctor identify an unusually fast heart rate (tachycardia) or an unusually slow heart rate (bradycardia). Heart rhythm.

An electrocardiogram is a graphic recording of your heart's electrical activity. Simply put, heartbeats are the result of this electrical activity in the cells of the heart.

An ECG records the electrical activity of the heart. The heart produces tiny electrical impulses which spread through the heart muscle to make the heart contract. These impulses can be detected by the ECG machine.

The ECG records the patterns of that electrical activity. 'Electrocardiogram' is often abbreviated 'cardiogram,' ECG, or EKG (Greek for heart is Kardio, hence the 'K' which is sometimes used instead of a 'C').

what information do we get from an electrocardiogram
From an electrocardiogram we can know the electrical activity of the heartbeat. We can get the electrical activity of the heartbeat from an electrocardiogram.
