However, an normal electrocardiography can not eliminate absolutely the heart disease. For example, in the case our heart rate is irregular and appears intermittently, if ECG is mearsured between the attacks, it will be normally. Also, not all cases of myocardial infarction were detected by normal ECG and angina is a typical case. At that time, we will need to consider a special ECG – Stress (Exercise) Echocardiography. Stress echo is done as part of a stress test. During a stress test, patients exercise or take medicine (given by doctor) to make their heart work hard and beat fast. A technician will use echo to create pictures of patients’ heart before they exercise and as soon as they finish. Some heart problems, such as coronary heart disease, are easier to diagnose when the heart is working hard and beating fast. To meet the demands of this procedure, a stress electro-cardiogram instrumentation wil be used in order to observe and store the whole process. Generally, such this system consists of three main units: exercise equipment (treadmill/stationary bicycle), special ECG device and a supported computer system. By considering appropriate components, a stress ECG instrumentation can be designed and integrated completely.
