Many tests help diagnose CHD. Usually, your doctor will order more than one test before making a definite diagnosis.
|
|
A definite diagnosis cannot be made from electrocardiography. About 50% of patients with significant coronary artery disease have normal resting electrocardiograms.
|

Did you know that electrical currents flow throughout your body? Because the strongest of these travels through your heart, doctors are able to monitor your heart by placing electrical sensors on the surface of your skin.
|
|
The ECG (also known as EKG) is a test that records electrical signals from your heart onto a paper strip. The pattern of these signals can tell the doctor whether your heart is normal, under stress, or experiencing electrical problems, strain, or damage.
|
|
The electrocardiogram(ECG) displays important information about the heart, including the occurrence of a heart attack or lack of oxygen, whether conduction of the heartbeat is disturbed, or its rate or rhythm altered. It is useful as a rapid indic...

|
|
An exercise stress test shows your heart's response to exercise. The test records your heartbeat while you walk on a treadmill or ride a stationary bike. It can be done in a hospital, a test center, or a doctor's office. The test is also called a stress electrocardiogram (ECG/EKG).
|

Holter monitoring is continuous monitoring of the electrical activity of a patient''s heart muscle( electrocardiography) for 24 hours, using a special portable device called a Holter monitor. Patients wear the Holter monitor while carrying out thei...
|
|
Detailed information on Holter or event monitoring When symptoms such as dizziness, fainting, low blood pressure, prolonged fatigue, or palpitations continue to occur without a definitive diagnosis obtained with a resting electrocardiogram (ECG), your child's physician may request an ECG tracing to be run over a long period of time. Certain arrhythmias (a fast, slow, or irregular heartbeat) which can cause the symptoms noted above may occur only sporadically, or may occur only under certain conditions, such as stress. Arrhythmias of this type are difficult to obtain on an ECG tracing that only runs for a few minutes.
|
|
Holter monitoring is a painless way to record your heartbeat away from the doctor's office. It is a small electrocardiogram (ECG) that you carry with you. Holter monitoring records your heartbeat for your doctor to review at a later time.

|
|
Stress echocardiography, or stress echo, is a test that records images of your heart before and after exercise. By comparing the images, your doctor can tell whether your heart is getting enough blood to meet its increased demand for oxygen.
|
 |
An arteriogram is an imaging test that uses x-rays and a special dye to see inside the arteries. It can be used to see arteries in the heart, brain, kidney, and many other parts of the body.
|
 |
Angiography is the x-ray(radiographic) study of the blood vessels. An angiogram uses a radiopaque substance, or contrast medium, to make the blood vessels visible under x ray.
|
|
Angiography is a special type of x-ray that allows your coronary arteries to be viewed and recorded on film. Your doctor can see if the blood vessels to your heart are clogged.
|
|
CTA creates images of arteries throughout the body. A contrast medium (x-ray dye) is injected to make the blood vessels stand out. Pictures are then taken with the CT scanner. The CT images are processed by a computer to make a three-dimensional picture.

Talk to your doctor about the risks and complications of angioplasty. Peripheral angioplasty is a procedure that helps open blockages in peripheral arteries. These vessels carry blood to your lower body and legs.
|
|
Women who suffer from chest pain but show clear arteries on an angiogram may have a different type of blocked artery, where plaque builds up evenly on the inner surface or bulges outward.
|
|
Hepatic angiography is an x-ray study of the blood vessels that supply the liver. The procedure uses a catheter (thin, flexible tube) that is placed into a blood vessel through a small incision. A specially trained doctor called an interventional radiologist usually does the procedure.
