Abstract
Systems and techniques relating to monitoring physiological activity using partial state space reconstruction. In general, in one aspect, a partial state space is produced using an orthogonal, frequency-independent transform, such as Hilbert transform. The partial state space can then be analyzed using state space techniques to identify physiological information for the biological system. The described techniques can be implemented in a distributed cardiac activity monitoring system, including a cardiac monitoring apparatus, and a QRS detector thereof.
