Abstract

This report describes the application of the biomedical theory and communication theory in the medical field. This project was proposed to help and assist those with heart problem especially for those elderly people. Heart attack may happen during the absence of their children from home which may result in death. Therefore, an Abnormal Heart Beat Detector may help to avoid such accidents as the device can detect mild attack. When the attack happens, it will automatically send an alarm signal to their children or neighbours via wireless communication. The scope of study for this project is narrowed down to the people with the abnormal heart beat (arrhythmia). Abnormal heartbeats occur when the heart has an irregular heart rhythm, beats too fast (Tachycardia), or beats too slow (Bradycardia).There are three important parts in this project. The first part is the sensor's circuit where an infrared light sensor is use and not harmful to human body. It must have the ability to sense mild heart attack. The second part of the project is the circuit design. This circuit is design using the PSpice and Multisim software for simulation. The main concerned on this circuit is that the device must be small enough in order to make it easy to be taken anywhere. The third part is the transmitter and the receiver circuit. These two circuits must be able to send and receive the alarm signal by using the proper modulation or method.
