4.2 ECG Module
Service Data
Power Freq shows the mains frequency selected: 50 Hz
/ 60 Hz
Cable type shows the leadwire set connected: 3 lead /
5 lead
Quick Zero shows 1 when the ECG signal is beyond
scale, and therefore, is quickly returned to the optimal
range with fast signal processing methods.
Artifact shows 1 when artifacts are detected.
Electrode shows ON when each of these electrodes is
connected.
Pacer count is a running number of detected
pacemaker spikes.
R count is a running number of detected R waves.
Resp: Avail shows if a module with impedance
measurement is plugged (1) or not plugged (0) into the
monitor.
Value shows the measured respiration rate value for impedance respiration.
Zeroing indicates the zeroing status of the respiration measurement: 1 = zeroing, 0 = not zeroing.
MeasOff shows 1 if the respiration measurement is set to OFF, and 0 if the the respiration
measurement is set to ON.
Arrhythmia shows an active arrhythmia alarm (VFIB, VTAC, ASY).
On/Off shows 1 if arrhythmia analysis is active and 0 if it is not active.
HR, HR25 and HR75 for R&D purpose only
QRS count shows the running number of detected QRS complexes.
PVC shows the PVCs detected per minute
Det leads shows the leads that are being used for detecting beats and ventricular fibrillation. The
selection of user leads (ECG1, ECG2, ECG3) on the monitor affects the leads used for detection. The first
lead used for detection is lead either I or II. The algorithm uses the lead appearing first in user leads. The
second lead used for detection is one of the precordial leads (V1 - V6): -1 = invalid (not used), 0 = lead I,
1 = II or III; 2 = V1, 3 = V2, 4 = V3, 5 = V4, 6 =V5, 7 = V6
nroleads shows the number of leads that are beign used for detecting beats and ventricular fibrillation.
Possible values include: 0 , 1 and 2 (ref. Det leads ) analysis.
Data for R&D purpose only
Noise M/A for R&D purpose only
Timeouts is a cumulative number that indicates how many times the module has not responded to the
monitor’s inquiry. Bad checksums is a cumulative number that indicates how many times
communication from the module to the monitor has broken down.
