Example 9 - Asystole Alarm Not Called
Problem
There is a pause of 2.837 seconds, but the system did not call an Asystole alarm. The
arrhythmia software algorithm detects asystole after a period of 3.0 seconds during
which no QRS has been noted. This example is below that 3.0 second threshold.

Example 10 - V-TACH Alarm Not Called
Problem
The patient had an episode of V-TACH, but the system did not call a V-TACH alarm.
The laser output with Lead I, II, and V shows that the system was learning when this
event occurred. That is the reason why this event did not alarm. ASYSTOLE and V-
FIB are the only events that supersede the Learn mode to create Level 1 alarms.
