Design and Development of ECG Simulator and Microcontroller Based Displayer

Cardiovascular disease is one of the major causes of mortality among developed societies. Therefore, an Electrocardiograph (ECG) device is one of the most important diagnostic devices in the medical field. Using this device, can be record and analyse electrical waves created in the heart and treat and treat cardiovascular disease. An ECG recorded electrocardiogram contains P wave, PR interval, QRS complex, ST segment, T wave, QT interval and U wave. Any changes in the ECG chart represent a type of cardiovascular disease. Using the ECG simulator, can be simulate the vital signal of the human heart and use it to inspect the correct functioning of the ECG device. Due to the fact that all medical devices are directly related to the patient, they should be checked for safety and accuracy, so that there is no risk to the patient and no problem to the diagnosis of heart disease. This article examines the Manufacture of an ECG simulator with an LCD (liquid-crystal display) that can display heart signals using this simulator.
