Android based heart rate monitoring and automatic notification system

In this paper, the design of an integrated portable device that can monitor heart rate (HR) continuously and send notifications through short message service (SMS) over the cellular network using Android application is presented. The primary goal of our device is to ensure medical attention within the first few critical hours of an ailment of the patient with poor heart condition, hence boost chances of his or her survival. In situations where there is an absence of doctor or clinic nearby (e.g., rural area) and where the patient cannot realize their actual poor heart condition, is where our implemented system is of paramount importance. The designed system shows the real time HR on the mobile screen through Android application continuously and if any abnormal HR of the patient is detected, the system will immediately send a message to the concerned doctors and relatives whose numbers were previously saved in the Android application. This device ensures nonstop monitoring for cardiac events along with notifying immediately when an emergency strikes.
