This report describes the application of the biomedical theory and communication theory. The project is proposed to help the problem that occurs to elderly person especially to the person with heart problems. When heart attack occurs during the absence of their children, the consequences might be death. Thus, a Heart Failure Detector device will be very useful to the children who always leave their old parents alone especially to heart problem parents. When the attack occurs, it will automatically send an alarm signalto their childrenor neighbours via wireless communication. The scope of study for this project is narrowed down to the people with the abnormal heartbeats (arrhythmia). Abnormal heartbeats occur when the heart has an irregular heart rhythm, beats too fast (tachycardia), or beats too slow (bradycardia). This may result in feeling light headed, tired or faint. The circuit is design and simulate using the PSpice and Multisim simulation software. The circuit is made small and compact enough in order to make it easy to be taken anywhere. An infrared light emitter with the wavelength of approximately 940nm is use to measure the pulsatile blood volume changes. The pulsatile signal that is receivedby a phototransistor is then amplified by an Op-ampand the counter will be the analyzer to differentiate between the normal heartbeat and abnormal heartbeat. The last part is the transmitter and the receiver circuit. These two circuits are able to send and receive the alarm signal using radio frequency (RF) modulation. The alarm receiver part is the part where all the alert routines are done such as dialling the emergency number and activating the siren.
