Cardiology diagnostic tests and procedures
The
diagnostic tests in cardiology are methods of identifying
heart conditions and related
pathology that results in abnormal heart function. Some modern techniques include:
Auscultation
- Auscultation employs a stethoscope to detect abnormalities and heart murmurs.
Blood tests
- A variety of blood tests are available for analyzing cholesterol, HDL, LDL, triglycerides, homocysteine, and C-reactive protein to assess risk of coronary artery disease.
Coronary catheterization
- Coronary catheterization uses pressure monitoring and blood sampling through a catheter inserted into the heart through blood vessels in the leg to determine the functioning of the heart, and, following the injection of radiocontrast dye, uses X-ray fluoroscopy to determine position and size of heart and its chambers. Coronary angiography is used to determine the patency and configuration of the coronary arteries.
Echocardiogram
- Echocardiography uses ultrasonic waves for continuous heart visualization.
Electrocardiogram
- Electrocardiography (EKG) monitors electrical activity of the heart.
Holter monitor
- A Holter monitor records a continuous EKG for 24 hours or more.
Stress testing
- Stress testing is used to determine to assess cardiac function and to disclose evidence of exertion-related cardiac hypoxia. Radionuclide testing using thallium or technetium can be used to demonstrate areas of perfusion abnormalities.
