An ECG based Arrhythmia Detector with an emergency alert system

Abstract

Cardiac arrhythmia is an abnormal heartbeat or rhythm. The heartbeat rate becomes too fast or when the heartbeat rate is irregular, the ability of the heart to pump blood will be affected. This will eventually reduce the blood flow through the brain which may result in loss of consciousness, dizziness, or even death if the required procedures are not carried out in time. The main aim of the proposed work is to alert some person or people nearby when a patient has an irregular heartbeat. The proposed work implemented Electrocardiogram integrated with micro-controller that monitor the heartbeat of a person and detects the type of arrhythmia, bradycardia or tachycardia based on the heart rate. The threshold set for bradycardia is 60bpm and for tachycardia is 100bpm. The system detects for the irregularity in heartbeat, which could later lead to an unanticipated event. Since the patient experiencing the attack is powerless during his/her sleep, an alarm is provided which is triggered and SMS is sent to registered mobile number with temperature, pulse rate and SpO2 values with type of arrhythmia in case of abnormality. This would alert people around the patient and then necessary immediate would be taken. The vital values are displayed on LCD.
