Electrocadiogram (ECG)

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 heart disease.


Tread Mill Test

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."
