THIS GUIDE IS INTENDED FOR REFERENCE ONLY. REFER TO INSTRUCTIONS FOR USE MANUAL.ADDITIONAL INFORMATION
In paced patients if the monitor sees a tall, narrow QRS as a pacer
spike, it may be undercounting the HR because it does not see a
subsequent QRS.
To correct undercounting with a three lead electrode set:
1.
Ensure that the LL (red) is on anterior axillary line at the lower
rib.
2.
Increase the gain to 0.50 or 0.25.
DOUBLE-COUNTED HEART RATE
If the monitor is “double-counting” the patient’s heart rate, a pos-
sible cause is a large P or T wave is being counted as a QRS complex.
To correct with a six lead electrode or five lead electrode set:
1.
View all leads and select to monitor processing for arrhythmia
detection the ECG leads that provide a smaller P or T wave
(the QRS complex must be more than double the size of the P
or T wave).
2.
Turn down detection sensitivity (gain).
3.
Select processing for arrhythmia detection in just one lead if
only one satisfactory lead is available (patient must be closely
monitored for this scenario).
4.
Reposition patient electrodes and Relearn (on large or very
small patient’s move white (RA) and red (LL) electrodes to-
wards apex of heart).
To correct with the three lead electrode set:
1.
Ensure that the LL (red) is on anterior axillary line at the lower
rib.
2.
Decrease the detection sensitivity (gain).
VENTRICULAR ALARMS FOR NORMAL RHYTHMS
If the monitor signaling ventricular alarms in a state of Normal Sinus
