All information contained herein is subject to the rights and restrictions on the title page.
Examples
Many of the types of false positive calls are related to electrode application and signal 
quality. Let’s consider several examples.
Example 1 - False High PVC Alarm
Problem
High PVC alarm occurs but no PVCs are present.
Fig. 93. Example 1 - False Positive Call
Correction
Press the Re-learn button to discard the patient’s previous templates and 
replace them with the current templates.
Check for dry electrodes. It may be time to replace them.
Least preferable, but still a possible solution: select a higher value for the 
PVC alarm or temporarily turn off the “High PVC” alarm.
Example 2 - False Arrhythmia Alarm
Problem
Alarms are occurring, but no abnormal arrhythmias are present. The patient’s intrinsic 
QRS has a high degree of variability that is associated with the following:
Atrial Fibrillation/Flutter with aberrant conduction
Intermittent or sustained right or left bundle branch block
Cardiomyopathy
