Patent ID: 8725258

Claim:
A cardiac rhythm management system, comprising: a hemodynamic sensor adapted to sense a signal indicative of hemodynamic performance; a tachyarrhythmia detector adapted to detect a tachyarrhythmia and determine whether the detected tachyarrhythmia sustains during an arrhythmia detection duration; and a duration controller coupled to the tachyarrhythmia detector, the duration controller including: a duration timer adapted to initiate and time the arrhythmia detection duration in response to a detection of the tachyarrhythmia; and a duration adjuster coupled to the duration timer, the duration adjuster including: a duration initialization module adapted to automatically determine an initial value using one or more indication parameters each indicating likeliness of occurrence of a tachyarrhythmia and set a base value of the arrhythmia detection duration to the initial value, the one or more indication parameters including patient demographics; and a dynamic duration adjustment module adapted to dynamically adjust the arrhythmia detection duration using the signal indicative of hemodynamic performance during the arrhythmia detection duration.
