6.1.4 R-R Analysis Mode
The R-R analysis mode contributes to get the related indicators of HRV (Heart Rate Variability).
HRV analysis refers to the variability between durations of the two following heart rates, and it is
a predicted indicator to sudden death caused by acute myocardial infarction and vicious
arrhythmia. For healthy persons, RR Histogram presents open and multi-peak; for patient with
the low variability caused by cardiovascular diseases (such as myocardial infarction or heart
failure), RR Histogram presents a single peak.

key again can stop printing the ECG report.
NOTE
: In the R-R analysis mode, you cannot set the speed. The constant speed is
25mm/s and the printing speed is 5mm/s, because in the R-R analysis mode, the
ECG wave length is compressed to one fifth of the original wave length.
