5.6.9 Adjusting the QRS 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:
1. Select the ECG parameter area to enter the [ ECG Setup ] menu.
2. Select [ Others >> ]
→
[ QRS Volume ]. The heartbeat volume can be set between 0 and 10, in which 0
means off, and 10 is the maximum volume.
You can also change the QRS volume by selecting [ ECG Setup ] through the Configuration Main menu.
When a valid SpO
2
value exists, the system will adjust the pitch of the heartbeat tone according to the SpO
2
value.
5.7 Arrhythmia Analysis
Arrhythmia analysis provides information about your patient’s condition, including heart rate and arrhythmia
alarms.
WARNING
•
Arrhythmia analysis program is intended to detect ventricular arrhythmias. It is not designed to
detect 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.
•
Atrial fibrillation (Afib) detection function is not intended for pediatric and neonatal patients.
•
Arrhythmia analysis is not intended for neonatal patients.
5.7.1 Understanding the Arrhythmia Events
Arrhythmia event Description Category
Asystole No QRS complex for 4 consecutive seconds (in absence of ventricular
fibrillation or chaotic signals). Lethal
arrhythmia
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
V-Tach 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.
