Echocardiogram is a test that uses sound waves to create a moving picture of the heart. The picture is much more detailed than x-ray image and involves no radiation exposure.
|
|
|
Echocardiography is a diagnostic test that uses ultrasound waves to create an image of the heart muscle. Ultrasound waves that rebound or echo off the heart can show the size, shape, and movement of the heart ' s valves and chambers as well as the flow of blood through the heart.

Right heart vetriculography is a study of the right chambers (atrium and ventricle) of the heart. This test is used to obtain measurements of pressure, oxygen, and cardiac output through a catheter (thin flexible tube). Occasionally, visualization of the right chambers is also necessary. This is obtained by injection of contrast media through the catheter into the right side of the heart with a rapid succession of x-rays taken to capture images of blood flow.

A tomogram refers to a slice, or section, which is imaged by moving the X-ray tube and recording film simultaneously and in opposite directions. This method serves to blur out structures in front of and behind the area of interest.

Computed tomography (CT) of the chest is performed to diagnose a variety of symptoms, including vascular, cardiac, airway disease as well as cancers that can occur in the thoracic region of the body. Purpose The purpose of the CT scan is to noninvasively and quickly visualize internal organs which may be damaged by disease or trauma.

An electrocardiogram (ECG) is a test that records the electrical activity of the heart. ECG is used to measure the rate and regularity of heartbeats as well as the size and position of the chambers, the presence of any damage to the heart, and the effects of drugs or devices used to regulate the heart (such as a pacemaker). See also stress test and Holter monitor (24h) .
|
|
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 indicator of the diagnosis and it is easy, painless, and inexpensive to record.

|
|
Electrocardiography is a commonly used, noninvasive procedure for recording electrical changes in the heart. The record, which is called an electrocardiogram (ECG or EKG), shows the series of waves that relate to the electrical impulses that occur during each beat of the heart.
|
|
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. They do this by giving you an electrocardiogram -- abbreviated either ECG or EKG (from the original German spelling of the word).
|
|
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.

An exercise stress test is a general screening tool to test the effect of exercise on your heart. The test gives a general sense of how healthy your heart is. During the test, the electrical activity of the heart is measured while you walk on a treadmill or pedal a stationary bicycle. This measures the heart's reaction to your body's increased demand for oxygen. (See also sestamibi and thallium stress tests .)
|
|
Used to evaluate heart function, a stress test requires that a patient exercises on a treadmill or exercise bicycle while his or her heart rate, breathing, blood pressure, electrocardiogram (ECG), and feeling of well being are monitored. Purpose When the body is active, it requires more oxygen than when it is at rest, and, therefore, the heart has to pump more blood.
|
|
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).

|
A stress test is primarily used to identify coronary artery disease . It requires patients to exercise on a treadmill or exercise bicycle while their heart rate, blood pressure , electrocardiogram (ECG), and symptoms are monitored.

Coronary angiography is a procedure in which a contrast material that can be seen using x-ray equipment is injected into one of the arteries of the heart. This allows your health care provider to view the flow of blood through your heart.
|
|
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.
|
|
Computed Tomography Angiography (CTA)CTAcreates images of arteries throughout the body. Acontrast medium(x-ray dye) is injected to make the blood vessels stand out.

Angiography is the x-ray study of the blood vessels. An angiogram uses a radiopaque substance, or dye, to make the blood vessels visible under x ray .

Thallium and sestamibi stress tests are nuclear imaging methods that provide a view of the blood flow into the heart muscle. The thallium and sestamibi tests are also called ?MIBI stress test? and ?myocardial perfusion scintigraphy?, and are used to evaluate how well your heart is perfused (supplied with blood) at rest as compared with activity. During these tests, heart images can be obtained because the patient receives an injection of a substance that is labeled with a radioactive marker or radiotracer to make it visible in the bloodstream. These substances are also called radiopharmaceuticals, and include thallium-201 and technetium-99m MIBI or sestamibi. In comparison to the standard treadmill stress test , thallium and sestamibi stress tests are more accurate and provide additional information.

|
A thallium heart scan is a diagnostic test that uses a special perfusion-scanning camera and a small amount of thallium-201, a radioactive substance, injected into the bloodstream to produce an image of the blood flow to the heart. Purpose A thallium heart scan is used to evaluate the blood supply to the heart muscle.
|
|
Cardiac nuclear imaging is also called a “perfusion scan.” A radioactive tracer is delivered into the bloodstream. Then a camera scans the tracer in the blood as it flows through the heart muscle.
|
|
The technetium heart scan is a non-invasive nuclear scan that uses a radioactive isotope called technetium to evaluate blood flow after a heart attack. Purpose The technetium heart scan is used to evaluate the heart after a heart attack.

The technetium heart scan is a noninvasive nuclear scan that uses a radioactive isotope called technetium to evaluate blood flow after a heart attack . Purpose The technetium heart scan is used to evaluate the heart after a heart attack.

During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body) Palpation (feeling the body with hands) Auscultation (listening to sounds) Percussion (producing sounds)

Lipid tests routinely performed on plasma include measurement of total cholesterol, triglycerides, high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein (LDL) cholesterol. Lipid tests may also be performed on amniotic fluid and include tests for lecithin and other pulmonary surfactants.

Lipid tests are routinely performed on plasma, which is the liquid part of blood without the blood cells. Lipids themselves are a group of organic compounds that are greasy and cannot be dissolved in water, although they can be dissolved in alcohol.
