have no intrinsic upper IBI limit, and the system can estimate post-recording
whether each recorded inter-beat-interval is likely correct or not based on the
magnitude and timing consistency of surrounding peaks.
As a result, IBI data recorded using an Actiheart 4 will be opened using a legacy
version of the IBI analysis function. This contains many of the same functions as
the current version, but with the 2000ms limitation, and no ability to ignore
specific noisy IBI samples within an otherwise good analysis epoch.
It is also possible to open Actiheart 5 recordings using the legacy analysis
function by selecting the option to do so from within the Utilities window. This is
not recommended for normal use, but may be useful to maintain consistency with
a project which has already begun.
3.3 Long Term
Recording
The long term recording mode is optimised for lower-resolution analysis of longer
time periods of a week or more. When the Actiheart 5 is set up from here, it will
track every single IBI and the acceleration waveforms as for IBI Monitoring mode,
only the focu
s of the analysis window is different. Data collected from “Long
Term” mode may be freely used in IBI Monitoring or any of the energy
Expenditure functions. It may also be opened in the Full Waveform analysis
window, but the ECG form available will be limited.
3.3.1 Setting
up a Long
Term
Recording
A recording is set up using the Setup button in the bottom-left of the window. For
further details, please see the Guide to Getting Started. If the user is not yet set
up in the database, please set up a new user as described in that guide also.
