Cardiovascular disease is one of the leading causes of death around the world. Telemedicine has a great impact in the cardiac monitoring of patients in remote environment. A wireless electrocardiograph monitoring system is implemented with Zigbee module for remote monitoring of cardiac patient. ECG Acquisition system is designed and the signals are plotted into the PC using MATLAB. The Signal from ECG acquisition module is given to Zigbee module. The transmitted signals are then received by Zigbee Transceiver. TTL output from the receiver Zigbee module is connected to the PC. The serial data are then plotted in Laptop using MATLAB. The controlling device of the whole system is a PIC microcontroller. ZIGBEE transmitter and receiver modules, ECG plates are interfaced to the PIC microcontroller. Microcontroller will continuously monitor the ECG signals from sensor and it will transmit over ZIGBEE transmitter and this dt received by ZigBee receiver and display into the PC using MATLAB GUI.    

The main objectives of the project are:  

1. Continuous ECG signal monitoring.
2. Wireless data transmission using Zigbee Technology.
3. MATLAB GUI based ECG signal plotting on PC.

    The major building blocks of the project are:  

• Regulated power supply.
• PIC Microcontroller.
• Reset Button
