Context-aware HRV analysis system

With the availability of ubiquitous healthcare based on wireless sensor network, heart rate variability (HRV) analysis, as a valuable evaluation tool of cardiovascular mortality should be utilized more pervasively and accurately. We propose a ubiquitous HRV analysis system using people´s daily life heart monitor data. The system consists of a sensor node recording electrocardiography (ECG) and acceleration signals, a processing node which does online processing and local storage, and a central server for storage, monitoring and data mining. The transmission of data between them is wireless. Data representation, storage, retrieval and processing are discussed. Planned inner/inter person data mining is also introduced. Experimental results verified the basic system functions and the research idea.
