“…The output of the adder circuit is connected to the ADC pin of the microcontroller to be converted from an analog signal to a digital one. The modified data are then processed on the microcontroller and the microcontroller will control the multiplexer (two-way communication between the microcontroller and computer) [23]. After the processing in the microcontroller, the data are sent via communication between Bluetooth and the Delphi7 application on a computer and displayed it in the form of an ECG signal graph.…”

Based on data from Basic Health Research (Riskesdas) in 2018, the incidence of heart and blood vessel disease is increasing from year to year. At least 15 out of 1000 people or about 2,784,064 individuals in Indonesia suffer from heart disease. Therefore, cardiovascular health care can make a better diagnosis through continuous monitoring. The purpose of this study was to develop a 12-lead circuit, a lead selector (Wilson Central Terminal), an instrumentation booster, an analog filter (Notch Filter 50Hz), Arduino UNO, a Bluetooth module, and Delphi7 application to display electrocardiograph signals. The results show that the Bluetooth module cannot send a signal at a distance of 20 meters if there is no obstacle, cannot send a signal at a distance of 10 meters if there is an obstacle in the form of a wall, and cannot send a signal at a distance of 16 meters if there is an obstacle in the form of wood (doors).

The use of portable devices is increasing day by day. Mainly these devices play a vital role in medical field when the doctors are unavailable. In that one of the important emergency medical portable systems is Electro Cardiogram (ECG). ECGs are used to measure the abnormalities of the heart by performing electrical activities. It can be done by attaching electrodes on the body for few minutes. To collect the information from electrodes data acquisition system is used in ECGs or in any biomedical systems. The major challenge in implementing data acquisition system is the increase in power dissipation due to the excessive contact impedance of electrodes. As a solution to this, A CMOS 12 lead ECG data acquisition circuit is designed by using analog multiplexers is proposed in this paper. The proposed system is designed by using improved DTMOS based analog multiplexers and these works with a power supply of ±0.2 V with a dynamic voltage range from 1uv to 200mv with the Power dissipation of 140 nW.
