Electrocardiogram (ECG) is a diagnostic tool that is used to measure and display the heartbeat. Nowadays, hospitals still use the traditional ECG monitor machine. The traditional ECG monitor machine is still stationary. The hospital staff has to move the machine with its wires from one patient to another. The purpose of this work is to acquire, transmit and display the ECG signal. In this work, it can be divided into two stages. The first stage is how the ECG signal is acquired using electrodes. Electrode is a sensor that is used to collect electrical activity from the heart. Three limb leads, based on Einthoven’s Triangle theory will be used in this work. The signal collected by electrode will be amplified using instrumentation amplifier INA118 with the gain amplification, G = 9. After the first amplification, the signal will go through a band pass filter, which allows frequency from 0.5Hz to 150Hz to pass through. The signal is then amplified, using 741 operational amplifier with gain, G = 51 to boost the signal into more readable signal. The total amplification for the first stage was 459. The signal is then send to ADC for wireless transmission via XBee. In the second stage, the USB port or Serial port of the laptop will be configured using LabVIEW software so that the ECG signal can be received. The LabVIEW software was programmed to receive, read, and display the ECG signal received. The ECG signal is successfully transmitted wirelessly via XBee to a laptop without it losing its characteristic (PQRST wave).
