8.2.2.6 Monitoring ventricular tachyarrhythmias without delivering therapy
The Monitor zone may be used to program a range of rates for detecting ventricular
tachycardia without delivering therapies.
Figure 150. VT Monitor Detection parameters
When VT Detection is programmed to On, the Monitor zone can function as a diagnostic
zone to monitor for non-life-threatening VTs with cycle lengths longer than the VT detection
interval (see Figure 150).
When VT Detection is not programmed to On, a Monitor zone may be programmed to
monitor any ventricular tachyarrhythmia with a cycle length longer than the VF detection
interval.
Notes:
●
Detection of a VF, VT, or FVT episode terminates a VT monitor episode and suspends
the VT monitoring operation until the tachyarrhythmia terminates.
●
The programmed SVT discrimination features (Onset, Stability, PR Logic, and Wavelet)
are applied in the VT monitor zone.
8.2.2.7 Detecting non-sustained ventricular tachyarrhythmia episodes
If at least 5 beats fall within any programmed ventricular tachyarrhythmia detection zone
(but fewer than the programmed Initial Beats to Detect), the episode is classified as a
non-sustained VT (VT-NS). For example, if 5 or more intervals occur in the VT zone, but not
enough to detect a VT episode, a VT-NS is detected.
After the device has been interrogated, VT-NS episodes can be selected from the Episode
Log. For more information about the Episode Log, see Section 6.8, “Viewing Arrhythmia
Episodes data and setting data collection preferences”, page 166.
