ELECTROPHYSIOLOGIC TESTING
COMMANDED THERAPY METHODS
The ventricular 50 Hz Burst will be delivered up to 30 seconds as long as
the Hold for Burst button is held and the telemetry link is maintained.
The atrial 50 Hz Burst will be delivered up to 45 seconds as long as the
Hold for Burst button is held and the telemetry link is maintained.
NOTE: During Hold for 50 H z Burst pacing , the S1 interval is automatically
set to 20 ms and the decrement to 0. These v alues will not be displayed on the
screen.
4. To stop the burst delivery, release the Hold for 50 Hz Burst button. The
Hold for 50 Hz Burst button will become dimmed again.
5. To deliver additional 50 Hz Burst pacing, repeat these steps.
COMMANDED THERAPY METHODS
The commanded EP test methods, Commanded Shock and Commanded ATP,
may be delivered independently of the programmed detection and therapy
parameters. If the pulse generator is in the process of delivering therapy when
a commanded method is initiated, the EP Test function overrides and aborts
the therapy in process. If an episode is not in progress, then a C ommanded
Ventricular Episode will be recorded in the Arrhythmia Logbook. C ommanded
Shock and Commanded ATP delivery is inhibited when a magnet is positioned
over the pulse generator, if it is programmed to Inhibit Therapy.
Commanded Shock
The Commanded Shock feature allows delivery of a shock with programmable
energy and coupling interval.
All Commanded Shocks are Committed and delivered R-wave synchronously
when the coupling interval is programmed to Sync. Shock waveform and
polarity are identical to detection-initiated shocks but a programmed coupling
interval may be specified. The coupling interval is initiated at the point where
the shock would have been delivered in Sync mode, but is instead delivered at
the programmed coupling interval. Following any Commanded Shock delivery,
Post-sho ck Redetection is use d and post-shock pa cing is activated.
Performing Commanded Shock Delivery
1. Select the C ommanded Shock option.
