What does an EKG tell the doctor about you?
An electrocardiogram, also known as an EKG or ECG, is a safe, non-invasive test that helps your doctor monitor for heart disease.

An electrocardiogram, also called an ECG or EKG, is a simple, painless test that detects and records your heart's electrical activity. This test also is used to detect and study heart problems such as heart attacks, arrhythmia or irregular heartbeat, and heart failure.
What is the instrument used to measure an EKG?
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. A normal heartbeat on ECG will show the timing of the top and lower chambers.
What are 3 reasons a person would get an EKG?
- Get a baseline measurement of heart activity.
- Determine the cause of chest pain.
- Diagnose arrhythmias.
- Evaluate possible heart-related problems, including severe tiredness, shortness of breath, dizziness, or fainting.
- Diagnose inflammation of the heart or its lining (endocarditis)

How does your heart work?
Your heart is a four-chamber muscle that pumps blood to the rest of your body. The top two chambers are called the atria, and the bottom two chambers are called the ventricles. Your body naturally produces an electrical charge strong enough to cause the heart muscle to contract.
Who needs an EKG?

Why do you need an EKG?
If you have experienced chest pain, have high risk factors for heart disease or previous heart troubles, your physician may choose an EKG to help them gain insight into your condition. If problems are found to exist, additional tests may need to be performed in order to ensure a complete understanding of the circumstances, ...
How to do an EKG?
There are a few reasons why your physician may wish to conduct an EKG. These can include: 1 Check the heart’s rhythm 2 Identify any underlying cause of chest pain or pressure 3 Determine the cause of heart disease symptoms such as shortness of breath, dizziness, or palpitations 4 Identify structural problems of the heart’s chambers 5 Determine the effectiveness of heart medications or a pacemaker 6 Evaluate heart health based on other factors such as high cholesterol, high blood pressure, smoking, or diabetes
What is the most common test for heart disease?
And, while there are several potential tests that your physician could recommend, electrocardiogram (EKG) is the most commonly used.
What is diagnostic testing?
From echocardiograms to CT scans, diagnostic testing is a critical component in the detection and management of all forms of cardiovascular disease. These tests can give your cardiologist valuable insight into the overall health of your heart, as well as clues to potential problems.
What is the purpose of EKG?
Purpose of an EKG Test. An ECG detects your heart's electrical rhythm and produces what's known as a tracing, which looks like squiggly lines. This tracing consists of representations of several waves that recur with each heartbeat, about 60 to 100 times per minute. The wave pattern should have a consistent shape.
What is an EKG?
The electrocardiogram, also referred to as ECG, 12-lead ECG, or EKG, is a non-invasive diagnostic test that evaluates your heart's electrical system to assess for heart disease. It uses flat metal electrodes placed on your chest to detect the electrical activity of your heart as it beats, which is then graphed.

What are the conditions that can be detected when a doctor checks your pulse?
There are a number of conditions that can be detected when your doctor checks your pulse, such as tachycardia (rapid heart rate), bradycardia (slow heart rate), and arrhythmia (irregular heart rate). EKG wave patterns not only verify these alterations in heart rhythm, certain changes in the shape of the waves provides information about the specific type of heart disease and which region in the heart is affected.
Is ECG safe?
Limitations. The ECG is one of the most commonly used tests in medicine because it can screen for a large variety of cardiac conditions, the machines are readily available in most medical facilities, the test is simple to perform, is safe, and relatively inexpensive. That said, an ECG has its limitations:

This is called a "resting" EKG , although the same test may be used to check your heart while you exercise.
How to do a sex test?
Some things you can do to get yourself ready: 1 Avoid oily or greasy skin creams and lotions the day of the test because they can keep the electrodes from making contact with your skin. 2 Avoid full-length hosiery, because electrodes need to be placed directly on your legs. 3 Wear a shirt that you can remove easily to place the leads on your chest.

The actual measurement takes about one minute, or five minutes at most . Exercise ECG: Here the electrical activity of your heart is measured while you are physically active. This usually involves riding an exercise bike.
How long does a Holter monitor last?
Holter monitor: The electrical activity of the heart is typically recorded over a period of 24 hours. Three or four electrodes are attached to your chest, and a small recording device is worn on a belt or hung around your neck. The ECG data are then transferred to a computer later on at the doctor's office for analysis.
Where are the signals sent?
These signals are sent by a group of cells in the right atrium of the heart known as the sinoatrial node ( SA node), and they spread through the heart muscle tissue as tiny electrical impulses. This causes first the atria and then the ventricles of the heart to contract.
How often is blood pressure checked?
Your blood pressure is also checked regularly. Holter monitor: The electrical activity of the heart is typically recorded over a period of 24 hours. Three or four electrodes are attached to your chest, and a small recording device is worn on a belt or hung around your neck.
