This paper describes a wearable health monitoring system integrated into a broad telemedical infrastructure allowing high - risk cardiovascular patients to closely monitor changes in their critical vital signs and get experts feedback to help maintain optimal health status. Consistent with the major challenge to provide good quality and reliable health care services to an increasing number of people utilizing limited financial and human resources, we propose a person - based health care system which consists of wearable Commercial of-the-shelf (COTS) nodes. These nodes, already used in the hospital environment, are capable of sensing and processing Blood-Oxygen, Blood-Pressure, Electrocardiographs (ECGs) and other vital signs and can be seamlessly integrated into Wireless Personal Area Networks (WPANs) for ubiquitous real time patient monitoring.
