Cardiac rhythm management system with arrhythmia prediction and prevention
First Claim
1. A method, comprising:
- detecting a conditioning event statistically associated with the occurrence of an arrhythmia in a patient'"'"'s heart; and
, predicting the occurrence of an arrhythmia within a specified prediction time period if an estimated arrhythmia probability exceeds a specified threshold value, wherein the estimated arrhythmia probability is computed from a conditional arrhythmia probability associated with the conditioning event that is derived from past observations of instances in which the conditioning event occurs alone or together with an arrhythmia within a specified time period.

Abstract
A cardiac rhythm management system predicts when an arrhythmia will occur and in one embodiment invokes a therapy to prevent or reduce the consequences of the arrhythmia. A cardiac arrhythmia trigger/marker is detected from a patient, and based on the trigger/marker, the system estimates a probability of a cardiac arrhythmia occurring during a predetermined future time interval. The system provides a list of triggers/markers, for which detection values are recurrently obtained at various predetermined time intervals. Based on detection values and conditional probabilities associated with the triggers/markers, a probability estimate of a future arrhythmia is computed. An arrhythmia prevention therapy is selected and activated based on the probability estimate of the future arrhythmia.

48. A cardiac rhythm management system, including:
-
a sensing module for detecting conditioning events statistically associated with occurrences of arrhythmias; and
,an arrhythmia prediction module for predicting the o ccurrence of an arrhythmia within a specified prediction time period if an estimated arrhythmia probability exceeds a specified threshold value, wherein the estimated arrhythmia probability is computed from a conditional arrhythmia probability associated with the conditioning event that is derived from past observations of instan ces in which the conditioning event occurs alone or together with an arrhythmia within a specified time period.
