Method and device for providing anti-tachyarrhythmia therapy

摘要

Various system embodiments comprise at least one sensor input adapted to receive at least one sensed signal associated with a tachyarrhythmia, a feature set extractor adapted to extract at least two features from the at least one sensed signal associated with the tachyarrhythmia, a feature set generator adapted to form a feature set using the at least two features extracted by the feature set extractor, at least one generator adapted for use to selectively apply an anti-tachycardia pacing (ATP) therapy and a neural stimulation (NS) therapy, and a controller adapted to respond to the feature set. The controller is adapted to initiate the NS therapy when the feature set corresponds to criteria for applying the NS therapy to modify the tachyarrhythmia, and initiate the ATP therapy to terminate the modified tachyarrhythmia. Other aspects and embodiments are provided herein.

1. A system, comprising:
at least one sensor input adapted to receive at least one sensed signal associated with a tachyarrhythmia; a feature set extractor adapted to extract at least two features from the at least one sensed signal associated with the tachyarrhythmia; a feature set generator adapted to form a feature set using the at least two features extracted by the feature set extractor; at least one generator adapted for use to selectively apply a shock therapy, an anti-tachycardia pacing (ATP) therapy, and a neural stimulation (NS) therapy; and a controller adapted to respond to the feature set, the controller being adapted to initiate the shock therapy when the feature set corresponds to criteria for applying the shock therapy, initiate the ATP therapy when the feature set corresponds to criteria for applying the ATP therapy, and initiate the NS therapy when the feature set corresponds to criteria for applying the NS therapy, wherein the controller is configured to detect a ventricular tachycardia (VT), characterize the detected VT to distinguish between a moderately fast rate and a very fast rate, distinguish between a stable rhythm and an unstable rhythm and distinguish among significantly unstable hemodynamics, stable hemodynamics, and modest hemodynamic compromise, and initiate the NS therapy when the detected VT is characterized by a combination of all of the following: a moderately fast rate, an unstable rhythm and a modest hemodynamic compromise.
