Overview

Provides R-R interval reference values; leaves open clinical utility pending prospective validation.

Structured PICO

P
Population
174 healthy subjects aged between 16 and 89 years
I
Intervention
Bedside computer-based technique for measuring and analysing cardiac beat-to-beat intervals at rest, during forced deep breathing, and during the Valsalva manoeuvre
O
Outcome
R-R intervals and variation in interval lengthsurrogate

A bedside computer-based technique can effectively measure heart rate variability and establish normal ranges for cardiac autonomic function testing.
