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.
Is a procedure for recording the electrical activity of the heart?
This type of Echocardiography is done before and after exercise or injection of a drug that makes the heart work faster and harder. An electrocardiography device that includes a small portable cassette recorder worn around a patient’s waist or on a shoulder strap to record the heart’s electrical activity.
What is the process of recording electricity flowing through the heart called?
An electrocardiogram is a recording of the electrical activity of the heart.
What is an instrument used to record the electrical activity of the heart?
A cardiac event monitor is a device that you control to record the electrical activity of your heart (ECG). This device is about the size of a pager. It records your heart rate and rhythm.

What is called heart of heart?
SA node is located in right atrial wall below the opening of the superior vena cava. It initiates each cardiac cycle. This is also known as pacemaker or “heart of heart” because it functions as originator of cardiac impulse AV node is also called pace setter.
Can I drink coffee before an EKG?
Patients can expect
No food or drink items containing caffeine (coffee, tea, chocolate, cola) for at least 12 hours before the test. The patient may be advised to stop taking certain medications before the test.
What is the pathway of the heart?
Right side of the heart
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
Does heart produce electricity?
The heart generates its own electrical signal (also called an electrical impulse), which can be recorded by placing electrodes on the chest. This is called an electrocardiogram (ECG, or EKG). The cardiac electrical signal controls the heartbeat in two ways.
