An Arduino-based system using photoplethysmography and a 3G shield was successfully developed to continuously monitor heart rate and automatically send SMS alerts or make emergency calls upon detecting abnormalities.
An Arduino-based system using a PPG sensor and 3G shield was successfully developed to provide low-cost, remote heart rate monitoring and automated alerts for cardiac patients.
The heart rate is to be monitored continuously for the heart patients. This paper proposed a system that awakes to monitor the heart rate condition of the patient. This work includes two parts. 1) We developed an application to monitor the patient's heart beat and if the heart beat is abnormal, a message should be transmitted to the doctor using 3G shield. Thus, doctors could monitor the patient's heart rate condition continuously and suggests few earlier precautions to the patient. The heart rate is detected by using photoplethysmograph (PPG) technique. 2) The Arduino wireless communication is developed in such a way that it performs voice calls, sends SMS by interfacing with 3G shield using AT commands. One of the input given is a user specified number to be dial and the expected output is voice call should be successfully performed. Here the program is written in such a way that there are many options available like dynamic call, emergency call (police, ambulance, and fire), sending message, receiving call, Disconnect a call, Redial, Forward message.

L.V et al. (2016) studied Cardiac patients (intended). Arduino-based abnormal heart rate detection and wireless communication system was evaluated on System functionality (heart rate detection and SMS/call transmission). An Arduino-based system using photoplethysmography and a 3G shield was successfully developed to continuously monitor heart rate and automatically send SMS alerts or make emergency calls upon detecting abnormalities.
