Cardiac catheterization involves passing a catheter (a thin flexible tube) into the right or left side of the heart. In general, this procedure is performed to obtain diagnostic information about the heart or its blood vessels or to provide treatment in certain types of heart conditions. Cardiac catheterization can be used to determine pressure and blood flow in the heart's chambers, collect blood samples from the heart, and examine the arteries of the heart with an x-ray technique called fluoroscopy. Fluoroscopy provides immediate ("real-time) visualization of the x-ray images on a screen and provides a permanent record of the procedure.
|
 |
Cardiac catheterization (also called heart catheterization) is a diagnostic procedure which does a comprehensive examination of how the heart and its blood vessels function. One or more catheters is inserted through a peripheral blood vessel in the arm (antecubital artery or vein) or leg (femoral artery or vein) with x-ray guidance.
|
|
You may have had angina, dizziness, or other symptoms of heart trouble. To help diagnose your problem, your doctor may suggest having a cardiac catheterization. This common procedure is sometimes also used to treat a heart problem.
|
 |
Cardiac catheterization (also called heart catheterization) is a diagnostic and occasionally therapeutic procedure that allows a comprehensive examination of the heart and surrounding blood vessels . It enables the physician to take angiograms, record blood flow, calculate cardiac output and vascular resistance, perform an endomyocardial biopsy, and evaluate the heart's electrical activity.

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 screening tool to test the effect of exercise on your heart. The test gives a general sense of how healthy your heart is. See thallium and sestamibi 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.

 |
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.

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.

C-reactive protein is a test that measures the amount of a protein in the blood that signals acute inflammation.
|
|
I had a high-sensitivity C-reactive protein test that was 38.6, which my doctor said was quite high. My cholesterol was fine. A heart scan and stress test were normal. When my doctor repeated the test, my hsCRP was 6.1. What can cause such variations?
|
|
Serum myoglobin is a test that measures the amount of myoglobin in the blood. Myoglobin is a protein in heart and skeletal muscles. When a muscle is exercised, it uses up available oxygen. Myoglobin has oxygen bound to it, thus providing an extra reserve of oxygen so that the muscle can maintain a high level of activity for a longer period of time. When muscle is damaged, myoglobin is released into the bloodstream. Ultimately, it is excreted in the urine (see urine myoglobin.

|
Stress echocardiography is a test that helps diagnose heart disease with the help of ultrasound images. (A more routine exercise stress test does not use imaging) Following exercise or other stress to the heart, the images reveal parts of the heart that may not be receiving enough blood or oxygen because of blocked arteries. This test may be used to monitor your progress if you already have a known heart condition.
|
|
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.
|
|
Transesophageal echocardiography is a diagnostic test using an ultrasound device that is passed into the esophagus of the patient to create a clear image of the heart muscle and other parts of the heart. A tube with a device called a transducer is passed down into the patient ' s throat and into the esophagus (the food tube that connects the mouth to the stomach).
|
|
Detailed information on transesophageal echocardiography, also called TEE or heart scan with endoscopy, including reasons for the procedure, risks of the procedure, what to expect, and discharge instructions
|
|
Transesophageal echocardiography (TEE) is a test that allows your doctor to record images of your heart from inside your esophagus, or food pipe.
|
|
Transesophageal echocardiography (TEE) is a diagnostic test in which an endoscope with an ultrasound transducer at its tip is inserted into the patient ' s esophagus by means of a catheter (thin tube). Sound waves are transmitted and received by the transducer to produce a clear image of the heart muscle and other parts of the heart.
