Overview

May enable field assessment of cardiac vagal tone; leaves open validation against clinical outcomes before routine use.

Structured PICO

Population

11 healthy nonsmokers (5 males, 6 females), mean age 22.0 years, mean BMI 20.5 kg/m2.

Intervention

Paced breathing at constant frequencies (0.18-0.33 Hz) and nonpaced regular breathing, assessed at various times after meals.

Outcome

Respiratory sinus arrhythmia (RSA) amplitude (C-CVRSA) as a function of breathing frequency.surrogate

Standardizing respiratory sinus arrhythmia amplitude to a breathing frequency of 0.25 Hz provides a reliable, simple method for assessing cardiac parasympathetic activity during nonpaced breathing.

Limitations

Based on data for young, healthy, and nonobese nonsmokers
Remains to be determined whether the method can be applied to the aged, the obese and/or heavy smokers
