Cardiovascular diseases or heart diseases are conditions that affect the normal functioning of the heart. Some common diseases are; Coronary artery heart disease, Valvular heart disease, Cardiomyopathy, and Arythmias. Risk factors that increase the chances of a heart disease are Smoking, High Blood Pressure, High Cholesterol. Diabetes, Obesity and a Family history of heart disease. Most common symptoms of a heart disease are sharp chest pains, shortness of breath, sweating, nausea, vomiting, indigestion and fatigue. E.C.G. is the most commonly performed cardiac test to detect any cardiovascular diseases. This is because the E.C.G. is a useful screening tool for a variety of cardiac abnormalities. E.C.G. machines are readily available in most medical facilities, and the test is simple to perform, risk-free and inexpensive. During the E.C.G., you will lie on a examination table and 10 electrodes (or leads) will be attached to your arms, legs, and chest. The electrodes detect the electrical impulses generated by your heart, and transmit them to the E.C.G. machine. The E.C.G. machine produces a graph (the E.C.G. tracing) of those cardiac electrical impulses. The electrodes are then removed. The test takes less that 5 minutes to perform. The E.C.G. determines your heart rate, heart rhythm, whether there are “conduction abnormalities” (abnormalities in how the electrical impulse spreads across the heart), whether there has been a prior heart attack, whether there may be coronary artery disease or whether the heart muscle has become abnormally thickened. All these features are potentially important. If the E.C.G. indicates a heart attack or a possible coronary artery disease, further testing is often done to completely define the nature of the problem and decide on the optimal therapy. These tests often include a stress test and/or cardiac catheterization. If the heart muscle is thickened, an echocardiogram is often recommended to look for possible alular heart disease or other structural abnormalities. Changes in the electrical pattern on the E.C.G. may give clues to the cause of syncope (fainting), or may indicate underlying cardiac disease.
The department of Cardiology at U.S. Diagnostic Centre is well equipped with doctors for diagnosis and treatment of patients with heart conditions. Medical investigations such as E.C.G. and T.M.T. are carried out to screen cardiac diseases. For all tests conducted under this department, click on the Tests.
