|
|
|
|
a) Header Line
|
|
First Line of a valid file has to contain header information. This has to be a comma-separated
|
|
list of the measures provided in the data lines. You do not need to provide all possible measures,
|
|
but at least "timestamp_measure" and "rMSSD".
|
|
|
|
As mandatory field you need time/date of the measures:
|
|
- "timestamp_measure" - ISO8601 formatted Date/Time String
|
|
|
|
The mandatory measure is:
|
|
- "rMSSD" - Square root of the mean of the squares of differences between adjacent NN intervals
|
|
|
|
The optional measures are:
|
|
- "HR" - Average HR
|
|
- "AVNN" - Average of all NN interval
|
|
- "SDNN" - Standard deviation of all NN intervals
|
|
- "pNN50" - Percentage of differences between adjacent NN intervals that are greater than 50 ms
|
|
- "LF" - Power at Low Frequencies
|
|
- "HF" - Power at High Frequencies
|
|
- "HRV4T_Recovery_Points" - A log transform of rMSSD
|
|
|
|
Data formats:
|
|
- "date" is a ISO8601 formated date/time
|
|
- all other measures are float/double in format <xxxxxxx.yyy>
|
|
|
|
There are very strict format checks when importing. Only if the whole
|
|
file is correct the data is imported. Any error (even in a single entry)
|
|
will block the complete import.
|
|
|
|
The following error will stop the import.
|
|
- Unknown measures in header
|
|
- Number of measures in header is different to number in an item
|
|
- Item measure in wrong format
|
|
- "timestamp_measure" or "rMSSD" is missing
|
