System for monitoring and diagnosis of cardiac electrogram signals using multi-dimensional analysis

摘要

An analyzer automatically analyzes both, a common portion of multiple successive heart cycles of electrophysiological signal data synchronized with respect to a P wave and a common portion of multiple successive heart cycles of the signal data synchronized with respect to an R wave, to identify changes occurring in amplitude value and time duration of the common portion of the multiple successive heart cycles of the signal data. A display processor initiates generation of at least one display image showing the common portion of the multiple successive heart cycles synchronized in time, adjacent and mutually vertically displaced to facilitate visual comparison and highlighting an identified change by a visual attribute.

主权项

1. A system for analyzing cardiac electrophysiological signals, the system comprising:
an acquisition processor for acquiring signal data representing heart electrical activity over a plurality of heart cycles, an individual heart cycle comprising a plurality of different signal portions between successive sequential R waves; an analyzer for
automatically analyzing both,
a first sweep based on a common portion of a plurality of successive heart cycles of the signal data, wherein the successive heart cycles in the first sweep are synchronized with respect to a P wave, anda second sweep based on the common portion of the plurality of successive heart cycles of the signal data, wherein the successive heart cycles in the second sweep are synchronized with respect to an R wave, andsaid analyzer identifying changes occurring in amplitude value and time duration in the first sweep and in the second sweep; and a display processor for initiating generation of at least one display image showing the first and second sweeps synchronized in time to their respective P and R waves, adjacent and mutually vertically displaced to facilitate visual comparison, said display processor highlighting the identified changes in amplitude value or time duration by a visual attribute.
