ACRONYMS AND DEFINITIONS
BT
Bluetooth
(1)
: Generic term for naming all types of wireless interfaces according to Blue-
tooth consortium specifications (regardless of the Bluetooth protocol version).
BTLE
or
BT 4.0
Bluetooth®
(1)
Low Energy, also called Bluetooth 4.0., enables HookUp RS to commu-
nicate with Spider SAS.
ev Event button located on the front of Spider SAS. Intended for use by the patient when
he/she wants to highlight a particular moment (symptom or relevant moment). When
the button is pressed, Spider SAS creates a specific user mark which will be displayed
in Synescope 3.30 or higher.
HookUp
RS
Lets the users program the Spider SAS recorder and check the quality of signals from
the connected sensors.
R: Rhythm – S: Sleep.
HR
(bpm)
Heart rate trend. A mean heart rate curve is calculated every minute (light line) and
maximum and minimum values over the same period (dark line).
µSD Micro SD Card: delivered in plastic box with SD card adapter.
φ Hub Physio Hub.
SAS
Option
Software option embedded in Synescope 3.30 to analyze Spider SAS recordings.
Spider
SAS
SAS: Sleep Apnea System. Multi-settings recorder dedicated to sleep apnea (pauses
in breathing or shallow breathing while the patient sleeps).

ABBREVIATIONS (RHYTHM)
Brady Periods of bradycardia detected during a recording. Bradycardia threshold values can
be defined in the rhythm protocol. Bradycardia can only be detected if the mean rate is
lower than the threshold value for at least 10 seconds.
MB Missed Beat period detected during a recording. Equal to a rate reduction of 75% (i.e.
175% of the previous RR) compared to the mean rate. Missed beats are not detected
during segments of unstable rhythm.
Pause Pauses detected during a recording. The minimum duration of a pause is defined in the
rhythm protocol. Pauses between two artifacts are not detected.
RR
inst
RR interval instability, periods of irregular supraventricular cardiac rhythm detected dur-
ing a recording. These may be periods of atrial fibrillation, atrial flutter or sinus arrhyth-
mia.
SVPB
All supraventricular premature beats detected during a recording.
SVPB/1: one isolated supraventricular premature beat.
SVPB/2: pair of consecutive supraventricular premature beats.
SVPB/3: 3 or more consecutive supraventricular premature beats.
All isolated, couplets or runs are indicated in red.
Number of events detected per minute related to the trend bar’s height.
SVPB count during runs voluntarily stopped at 22 beats, necessary to minimize risk of
misdetection of events during false positive SVPB runs. The “MaxHR” value indicated
on the label of the run event is calculated on as many RR intervals as set for the calcu-
lation of Min/Max HR. If not enough RR values are available, 2 values are used.
