Diagnostic proceduresCardiovascular system By Loredana Lungu
Cardiac Scan• Patient is given radioactive thallium intravenously and then scanning equipment is used to visualize the heart. It is especially useful in determining myocardial damage
Cardiac Scan• During a cardiac CT scan, an x-ray machine will move around your body in a circle. The machine will take a picture of each part of your heart. A computer will put the pictures together to make a three-dimensional (3D) picture of the whole heart.
Echocardiography• Echocardiography was an early medical application of ultrasound. Echocardiography was also the ﬁrst application of intravenous contrast-enhanced ultrasound. This technique injects gas-ﬁlled microbubbles into the venous system to improve tissue and blood delineation.
Purpose• Echocardiography is used to diagnose cardiovascular diseases. In fact, it is one of the most widely used diagnostic tests for heart disease. It can provide a wealth of helpful information, including the size and shape of the heart, its pumping capacity and the location and extent of any damage to its tissues.
Holter monitor• Portable ECG(electrocardiography) monitor worn by a patient for a period of a few hours to a few days to assure the heart and pulse activity as the person goes through the activities of daily living.• Used to assess a patient who experiences chest pain and unusual heart activity during exercise and normal activities.
Holter monitor• Electrodes (small conducting patches) are stuck onto your chest and attached to a small recording monitor. You carry the Holter monitor in a pocket or small pouch worn around your neck or waist. The monitor is battery operated.
Consideration • While wearing the device, avoid: • Electric blankets • High-voltage areas • Magnets • Metal detectorsIt is very important for you to keep a diary ofsymptoms. The diary should include the date, time ofday, type, and duration of symptoms.
