A smartphone-based U-Healthcare system for real-time monitoring of acute myocardial infarction

In recent years, medical service has been evolving from systems designed around centralized hospitals to Ubiquitous Healthcare (U-Healthcare). U-Healthcare system can facilitate real-time monitoring of patient states, and can provide medical checkups and management whenever and wherever the medical staff deems necessary. U-Healthcare services can provide chronic condition monitoring in the early stages of diseases and help execute decisive medical action in emergencies. However, thus far, the application of U-Healthcare systems has been limited to diseases such as obesity, diabetes, etc. Acute myocardial infarction (AMI) is among the most critical chronic diseases and requires early detection and treatment. In this paper, we propose an AMI diagnostic software technique and protocol that can support real-time communication between the patient and medical personnel. Our monitoring and diagnostic system has been developed using a protocol based on ISO/IEEE 11073. When data is transferred from the patient's smartphone to a server in hospital, the medical personnel consult the patient's biosensor data to determine the status of the relevant disease and provide appropriate medical service. The relevant information is sent back to the patient's smartphone through a wireless network, and patients can view their data in graphical format through their smartphone.
