A Survey on Tracing Heart Attacks by Pulse Monitoring in IoT

Safeguarding one's health is optimal for longevity and a good life. Heart attacks have become so common amongst the public due to the lifestyle and food habits being followed. Early detection of an oncoming heart attack can help reduce seriousness of the incident and safeguard the patient's health. Technology has always been used in healthcare and has proved to be extremely beneficial. Internet of Things is a phenomenon that is utilized in day to day human activities. It is an interlinked collection of hardware devices, home appliances that are interfaced with electronics, software, sensors, and actuators. Internet is the backbone of connectivity and Things mean objects or devices. Sensors play a vital part in the field of IoT. To provide a system where heart attacks can be detected early, heart beats of the patient are monitored using a pulse sensor and a temperature sensor, which is then interfaced with a microcontroller. This sensor will be installed in a wearable device. When the heartbeat of the patient exceeds a certain threshold value, an alert will be sent to the remote family, and the medical authorities with the help of the Internet. Sensor is used for sensing the heart beats. The microcontroller receives these beats and evaluates pulse. If the pulses are above or lower than the threshold value, the microcontroller initiates WiFi module and sends out distress message to mobile contacts previously stored inside microcontroller.
