Heart failure stratification based on respiratory pattern

Abstract

Systems and methods for monitoring patients for risk of worsening heart failure (WHF) are discussed. A patient management system includes a receiver to receive patient respiration measurement. A respiratory pattern analyzer circuit measures respiratory pattern indicative of rapid-shallow breathing pattern from the received respiration measurement, and determine a respiratory pattern variability indicator. A risk analyzer circuit determines patient WHF risk using the respiratory pattern variability indicator. The system may use the WHF risk to guide WHF event detection, or to deliver or adjust a heart failure therapy.
