Cardiology is that branch of medicine which deals with the diagnosis and treatment of heart diseases. Cardiologists investigate patients with suspected heart disease by taking a very careful, extensive history of the patient's condition and performing a complete physical examination.
"Radiology is the science which deals with the use of radiant energy for the diagnosis and treatment of a disease. A minimally invasive form of medicare, it allows the doctor to study a patient's internal system, without making any cuts on the body".
An electrocardiogram is a recording of the small electric waves being generated during heart activity. A normal heart beat is initiated by a small Pulse of electric current. This tiny electric "shock" spreads rapidly in the heart and makes the heart muscle contract. If the whole heart muscle contracted at the same time, there would be no pumping effect. Therefore the electric activity starts at the top of the heart and spreads down, and then up again, causing the heart muscle to contract in an optimal way for pumping blood.
Echocardiography is a diagnostic technique that can provide a wealth of helpful information, including the size and shape of the heart, its pumping strength, and the location and extent of any damage to its tissues. It is especially useful for assessing diseases of the heart valves. Echocardiography can reveal such abnormalities as poorly functioning heart valves or damage to the heart tissue from a past heart attack. However, a normal echocardiogram does not rule out the possibility of coronary
An exercise electrocardiogram (EKG or ECG) is a test that checks for changes in your heart while you exercise. Sometimes EKG abnormalities can be seen only during exercise or while symptoms are present. This test is sometimes called a "stress test" or a "treadmill test."
Q. What is being tested?
A pulmonary function test (PFT) evaluates how well your lungs work. PFTs measure the amount of air in your lungs, how well the lungs move air in and out.
A respiratory therapist will guide you through each test in a special exam room that has all the lung function measuring devices. Most of the tests are quick, easy and painless, but be sure to tell the therapist if you feel light-headed, tired or uncomfortable.
How can I prepare?
Don't eat a heavy meal right before the test, and avoid caffeinated foods or drinks. Don't smoke or exercise strenuously for six hours before the test. On the day of the test, wear loose clothing that won't restrict your breathing, and wear dentures to the testing if you normally wear them. Finally, just relax, breathe easy and do your best.
Who Needs a Holter or Event Monitor?
Your doctor may recommend a Holter or event monitor if he or she thinks you have anarrhythmia. An arrhythmia is a problem with the rate or rhythm of the heartbeat.
Holter and event monitors most often are used to detect arrhythmias in people who have:
