Example 3 - Missed Ventricular Tachycardia
Problem
Sometimes the arrhythmia system calls a ventricular arrhythmia differently than the
clinicians would. Remember that the system has criteria which must be met. For
example, V-TACH is called when the rate is greater than or equal to 100 BPM and 3
consecutive PVCs are detected. If the ventricular abnormal varies, then the system
may mis-classify some of the beats as non-ventricular.

Correction
In these situations, the high heart rate limit may be decreased, which will provide
alarm notification. Enabling a lower level ventricular alarm may provide a safety fac-
tor for an alarm call, such as Couplet. This may be called before the system qualifies
the rhythm as V-TACH and would provide proper alarm notification to obtain the
attention of the system operator or caregiver.
