Abstract
Systems and methods are described herein for determining whether or not each of a plurality of cardiac signals monitored from a plurality of electrodes is stable. A dispersion signal may be generated based on the plurality of cardiac signals, and low dispersion time period may be selected within which the cardiac signals may be analyzed for stability.
Claims25
A system comprising:
- electrode apparatus comprising a plurality of electrodes to monitor electrical activity from tissue of a patient;
- and
- computing apparatus comprising processing circuitry and coupled to the electrode apparatus, the computing apparatus configured to:
- monitor electrical activity using the plurality of electrodes to generate a plurality of cardiac signals over an analysis time period,
- generate a dispersion signal from the plurality of cardiac signals, wherein the dispersion signal is representative of the dispersion of the plurality of cardiac signals over the analysis time period,
- select a low dispersion time period within the analysis time period based on rate of change of the dispersion signal, and
- determine whether each of the plurality of cardiac signals is stable based on the cardiac signal within the low dispersion time period.
