Coronary heart disease is caused by narrowing of Your coronary arteries with fatty deposits that tend to collect on your arteries. This innovative narrowing will present with symptoms in the future like chest pain and shortness of breath. Among the useful diagnostic tests for coronary Heart disease due to atherosclerosis is the electrocardiogram ECG, which measures the changes in electrical activity of the heart muscle with each beat. These modifications are detected by means of electrodes attached to the arms, one leg, and the front part of the chest. The heart’s electrical activity is displayed on a screen or recorded as a trace on paper. The ECG tracing from a normal, healthy heart has a characteristic shape, or waveform. Any irregularity in the heart rhythm or damage to the heart muscle is going to appear on the ECG trace as deviations from the normal waveform.
Recent technological advances have made the ECG an even More useful evaluation for heart disease, by allowing it to be completed while a man is following their everyday activities rather than, as previously, having to be done in doctor’s office or at the hospital. If you are suffering from attacks of chest pain That might be due to angina but the ECG listed on your doctor’s office is normal, you may be asked to undergo another ECG test when taking controlled exercise. First, a calculation is made according to your age, weight, etc. of your maximum safe heart rate. Then you are on the ECG machine and exercise by pedalling an exercise bike or walking on a treadmill until your heart is beating steadily in the calculated speed. This technique often reveals characteristic changes in the ECG pattern in people with narrowing of the coronary artery.
Another Kind of evaluations is the nuclear perfusion city x ray tilak nagar where traces of radioactive material thallium or technicism is injected and tracked down to your own heart to find out whether blood is adequately reaching your heart muscle. If the exercise ECG or nuclear perfusion tests are Found to be abnormal, your doctor may arrange for a coronary angiogram, where a special dye is injected into the coronary arteries so that they are clearly outlined in X-ray photographs. Whether this technique shows that the arteries are blocked or narrowed, regular circulation can frequently be restored by operation, such as coronary bypass grafting or Percutaneous Transluminal Coronary Angioplasty PTCA.
