An implantable cardioverter-defibrillator with automatic arrhythmia detection criteria adjustment

摘要

An arrhythmia detection system provides automatic detection criteria adjustment in an implantable cardioverter-defibrillator (30) that applies arrhythmia terminating electrical energy to a heart responsive to detection of the arrhythmic episode of the heart. A first detector (82) detects arrhythmic episodes of the heart in accordance with detection criteria. A second detector (90) confirms the detection of each arrhythmic episode by the first detector (82) and a detection criteria regulator (100) adjusts the detection criteria of the first detector responsive to confirmation results provided by the second detector.
