Prototype low-cost portable electrocardiogram (ECG) based on Arduino-Uno with Bluetooth feature

Abstract

World Health Organization (WHO) data stated that heart diseases cause 37% of deaths in Indonesia. In Indonesia, devices used to monitor the heart's activity or electrocardiogram (ECG) are only owned by some big hospitals. With an Arduino microprocessor, a simple portable ECG with a function to read the heart's condition could be made. The AD8232 sensor is the main device that is used to read the heartbeat by processing the voltage received from the electrodes attached to the body. Combination of Arduino-Uno and HC-05 FC-114 as a Bluetooth antenna, an ECG display could be seen on a smartphone's monitor in real-time. An ECG simulator is used as an artificial heart activity to be used as a trial for the ECG portable's performance from test results. ECG using the simulator can be delivered to the smartphone's monitor by Bluetooth module with an accurate result that draws the real-time condition of the patients.
