Nowadays, a few systems that provide a continuous health monitoring service for people or patient have been developed. However, the device is large and not mobile. A portable wireless technology heart rate monitor is a personal monitoring device which allows to measure and record heart rate for analysis at any time and any place wirelessly. This project objective is to implement an Electrocardiogram (ECG) and Digital Heart Rate counter using ZigBee wireless protocol and portable unit. The device is most useful if it is portable and it can be monitored from distant location. Generally, the project software application together with its Graphical User Interface (GUI) was developed using Microsoft Visual Studio in VB language for the computer platform. The microcontroller, PIC16F877A located on the main circuit board was programmed in C language using MPLAB IDE software and debugged together with the circuit design using Proteus 7 ISIS. The final prototype of the system was built to demonstrate the proposed functionality of the system. The limitation of this project is this device is able to detects the value of normal and abnormal condition only. It cannot detect the diseases and the category of diseases.
