Abstract

The ECG Simulator is a specialized device for testing and calibrating an electrocardiogram. Using this device, can be monitor electrocardiograms and fix possible errors and problems in the ECG device. Simulator can display heart signals in different algorithms and based on the signals generated, the electrocardiographic device is evaluated. Simulator has an important function in the development and design of an electrocardiograph and is an essential medical device.

This article examines an ECG simulator device with a graphic display that can display heart signals on a display, and is based on a microcontroller that is inexpensive compared to other ECG simulators, and has Architecture is simple.

Simulator designed based on two ICs 4521 and 4017, which is used for frequency division and counter. The quartz crystal to produce a proportional frequency, which is the frequency to set up ICs and Electrocardiograms, can be generated based on capacitor and resistor connections.

The displayer of this device is based on a microcontroller, which has a simple programming to indicate the signal obtained from the simulator on the LCD.
