System comprised of a medical device and method for analyzing physiological
and health data and representing the most significant parameters at different levels
of detail which are understandable to a lay person and a medical professional.
Low, intermediate and high-resolution scales can exchange information between each
other for improving the analyses; the scales can be defined according to the corresponding
software and hardware resources. A low-resolution Scale I represents a small number
of primary elements such as intervals between the heart beats, duration of electrocardiographic
PQ, QRS, and QT-intervals, amplitudes of P-, Q-, R-, S-, and T-waves. This real-time
analysis is implemented in a portable device that requires minimum computational
resources. The set of primary elements and their search criteria can be adjusted
using intermediate or high-resolution levels. At the intermediate-resolution Scale
II, serial changes in each of the said elements can be determined using a mathematical
decomposition into series of basis functions and their coefficients. This scale
can be implemented using a specialized processor or a computer organizer. At the
high-resolution Scale III, combined serial changes in all primary elements can
be determined to provide complete information about the dynamics of the signal.
This scale can be implemented using a powerful processor, a network of computers
or the Internet. The system can be used for personal or group self-evaluation,
emergency or routine ECG analysis, or continuous event, stress-test or bed-side monitoring.
