Abstract: Cardiovascular Disease (CVD) is the single foremost cause of mortality around the globe and is projected to stay so for a while. Cardiac Arrhythmia is a very common type of CVD and may contribute to an increased risk of stroke or sudden cardiac death. But, this can be averted now, due to the swift growth in technology. The proposed system utilizes a unique and efficient architecture for improving the existing healthcare systems by reducing the delay in medical attention with the help of Android-based mobile devices and a smart wearable with Bluetooth interface. This system focuses on building a real-time heart monitoring system considering the ease of application, cost, and accuracy. The system on the user (or patient) side mainly consists of various sensors for data acquisition, a microcontroller (e.g., Arduino), and software along with a smart device. The hospital side system will contain a Windows application which will be used to access the patient's data. The patient’s temperature, heart rate, blood pressure, blood glucose level and ECG data are continuously monitored, displayed, and stored by the system.The records of the patient will be synchronized to the central server to reflect the current status of the patient. The wearable device on detecting any abnormal readings will immediately report it to the smart device (mobile phone or tablet) which can further contact the nearest hospital, the listed Emergency contact, and the family doctor. Communication from a smart device (via the application) to hospital or family doctor will be using GSM Network.
