Abstract
Introduction: Coronary artery disease (CAD) is one of the common causes of morbidity and mortality all over the world. Its first clinical manifestation is acute myocardial infarction or sudden death .which has evolved slowly over many years without notable clinical manifestations. Detection of its presence at an early stage is essential in order to slow the evolution of disease. The value of electrocardiographic stress test as a non-invasive screening procedure for early detection of asymptomatic coronary heart disease or ischemia. Aims and Objectives: The present study was carried out in the department of medicine Government medical college and Hospital, Aurangabad to analyze the computerized stress test for – ischemia. Material and Methods: Patient referred for any reason included in study. A detailed history with clinical examination was carried out according to proforma. Computerized Treadmill Schiller’s Cardiovit CS-200 system was used for exercise test. Summary and Conclusions: Out of 100; 17 subjects grouped as positive test group having ST depression. 83 subjects who had no ST depression grouped together as negative test group. Amongst the ECG parameters, as duration of ST segment depression, time of onset of ST segment depression, leads showing ST segment depression, ‘R’ wave amplitude, QTc interval were significantly associated with a positive stress test, said to have coronary artery disease. Non-ECG parameters were significantly associated with positive stress test and parameters as delta heart rate, heart rate had no relation with the positivity of stress test.
