Abstract:
1. A system for heart performance characterization and abnormality detection, comprising: an acquisition device configured for acquiring an electrophysiological signal representing heart beat cycles of a patient heart; a detector configured for detecting parameters of said electrophysiological signal of parameter type comprising at least one of, (a) Principal frequency, (b) dominant frequency ratio and (c) frequency bandwidth, of first and second single different portions of a plurality of different portions of a single heart beat cycle of said heart beat cycles selected in response to first predetermined data, said first and second single different portions of said single heart beat cycle individually comprising single different portions selected from, a P wave portion, a QRS complex portion, an ST segment portion and a T wave portion in response to second predetermined data; a signal analyzer configured for calculating a ratio of the detected parameters of a single parameter type of the first and second single different portions; and an output processor configured for generating data representing an alert message in response to the calculated ratio exceeding a predetermined threshold.
