Actiheart Rate Variability Analysis

Actiheart Heart Rate Variability Analysis:

The Actiheart is ideally suited for Heart Rate Variability (HRV) and Inter-beat Interval (IBI) measurements in ambulatory settings.
The Actiheart can record IBI with 1ms resolution for 440,000 beats (approx. 3.5 days @ 76bpm).
The data is transferred to the Actiheart software which performs the Heart Rate Variability analysis.
The statistics calculated by the Actiheart software are based on 'Heart Rate Variability, Standards of Measurement, Physiological Interpretation and Clinical Use.' Task Force of the European Society of Cardiology and the North American Society of Pacing and Electrophysiology.

Some selected statistics include:

IBI Ave:
IBI Min, IBI Max:
LF & HF:

Average Inter-beat Interval (IBI) for the analysis epoch
Minimum and maximum IBI in the epoch
Standard Deviation of the IBI data
The low and high frequency component of the IBI, derived using an FFT
Occurrence distribution of IBI intervals
