A time domain approach for the fluctuation analysis of heart rate related to instantaneous lung volume
Key result
Analysis of 14 healthy male subjects revealed three components in the impulse response of heart rate to instantaneous lung volume: fast positive, delayed slow negative, and oscillatory.

Implication
May support autonomic research via refined HR-ILV impulse estimation; leaves open clinical validation and utility.
Structured PICO
P
Population
14 healthy male subjects evaluated for heart rate response to instantaneous lung volume fluctuations under various conditions.
E
Exposure
Autonomic blocking agents propranolol and atropine
O
Outcome
Transfer characteristics (impulse response) from fluctuations of instantaneous lung volume (ILV) to heart rate (HR)surrogate
A proposed time domain technique effectively estimates the impulse response of heart rate to instantaneous lung volume, identifying three distinct components modulated by autonomic tone.
