Design and Build ECG Simulator

ECG Simulator is a tool to simulate ECG signals. This device is useful for testing ECG devices when repairing, for research purposes on ECG signals or for educational purposes. ECG Simulator or often called Phantom ECG in principle is a signal generator in the form of ECG like signal or ECG signal that has been recorded. According to the researchers' observations, the ECG Simulator that was made there are still some shortcomings, namely PC-based, only 2 lead signals, limited BPM values and no sensitivity settings. Judging from the importance of using these tools as a standard ECG comparison tool, the researchers intend to design a tool entitled ECG Simulator Design. This design is based on Arduino and uses 12-bit Digital to Analog Converter to convert Digital data which is the output of Arduino into Analog data in the form of ECG signals. In this study, researchers made the design of the ECG Simulator which is a tool for calibrating ECG equipment. The purpose of this research is to design an ECG Simulator tool. The research design used was a study using a pre-experimental method with after-only design type of research because the final results of measurement tools compared with the control group. While this design through the stages as follows: circuit design and circuit testing. Based on the measurement results obtained an error rate of 0.420% sensitivity of 0.5mV, 0.22% sensitivity of 1.0mV, and 0.22% sensitivity of 2.0mV in the BPM setting 30, obtained an error rate value of 0.342% sensitivity of 0.5mV, 0.460% sensitivity of 1.0mV, and 0.432 % sensitivity of 2.0mV at BPM setting 60, obtained an error rate value of 0.121% sensitivity of 0.5mV, 0.1% sensitivity of 1.0mV, and 0.1% sensitivity of 2.0mV at setting BPM 120, obtained an error rate value of 0.423% sensitivity of 0.5mV, 0.310% 1.0mV sensitivity, and 0.520% 2.0mV sensitivity at 180 BPM settings and 0.246% 0.5mV sensitivity, 0.230% 1.0mV sensitivity and 0.246% 2.0mV sensitivity at 240 BPM settings.
