6.6.4 Adjusting Heartbeat Volume
In the case that ECG alarm is switched on, or both ECG alarm and PR alarm are switched off, heartbeat tone is issued.
To adjust the heartbeat volume,
„
Select the ECG parameter window to enter the [ ECG Setup ] menu, and then select [ Others >> ] [
→
QRS Volume ], or
„
From the Configuration Main menu, select [ ECG Setup ] [
→
QRS Volume ],
and then select an appropriate setting. The heartbeat volume can be set between 0 and 10, in which 0 means off, and 10
is the maximum volume.
When a valid SpO
2
value exists, the system will adjust the pitch of the heartbeat tone according to the SpO
2
value.
6.7 Arrhythmia Analysis
Arrhythmia analysis provides information about your patient’s condition, including heart rate and arrhythmia alarms.
NOTE
z
Arrhythmia analysis program is intended to detect ventricular arrhythmias. It is not designed to detect atrial
or supraventricular arrhythmias. It may incorrectly identify the presence or absence of an arrhythmia.
Therefore, a physician must analyze the arrhythmia information with other clinical findings.
z
The arrhythmia detection is not intended for neonatal patients.
6.7.1 Understanding the Arrhythmia Events
Arrhythmia event Description Category
Asystole No QRS complex for 4 consecutive seconds (in absence of ventricular fibrillation
or chaotic signals).
V-Fib/V-Tach A fibrillatory wave for 4 consecutive seconds.
A dominant rhythm of adjacent Vs and a HR > the V-Tach Heart Rate Limit.
Vtac The consecutive PVCs > Vtac PVCs limit, and the HR > the Vtac HR limit.
Vent. Brady The consecutive PVCs ≥ the Vbrd threshold and the ventricular HR < the Vbrd
Rate threshold.
Extreme Tachy The heart rate is greater than the extreme tachycardia limit.
Extreme Brady The heart rate is less than the extreme bradycardia limit.
Lethal
arrhythmia
PVCs/min PVCs/min exceeds high limit
PNP** No pace pulse detected for 1.75 x average R-to-R intervals following a QRS
complex (for paced patients only).
PNC** No QRS complex detected for 300 milliseconds following a pace pulse (for
paced patients only).
PVC One PVC detected in normal heartbeats.
Couplet Paired PVCs are detected.
VT>2 More than 2 consecutive PVCs within the last minute.
Nonlethal
arrhythmia
