NODAL_ERP
('n')
The NODAL_ERP study provides up to 3 auto-decremented extra-stimuli for AV Node refractory and
other measurements. S2-S4 may be auto-decremented by 50, then 20, then 10ms as Sx value
reduces from a Table accessed by Editing Decrement Parameter, or by an arbitrary single value set by
Decrement (disable decrementation Table by setting Config Var-11 to 0).

(VT Induction)
The MULTI_SX protocol provides up to 6 auto-decremented extra-stimuli primarily for programmed
ventricular stimulation. A warning message “Defibrillator Ready?” appears on entry to protocol if
pacing into Ventricle, its appearance is configurable by your distributor. In both above protocols,
manual adjustment of Sx suspends next auto-decrementation and the BSP key reverses last auto-
decrement.
SX property menu is opened on selected Sx using Ins/Edit and contains:
Enable first S1 Trigger from Sensed P/R or no trigger.
Enable AV delay for S1.
Set S1 AV delay time in ms.
Set individual S1 Train number control. The train value is displayed on the bottom of the Sx
button.
Enable individual S2- S7 auto-decrement for this Sx according to the common decrement
value set in the Stimulus Menu.
12.8.6 Wenckebach Protocol

('w')
TRAIN=4
S1
The WENCKEBACH protocol continuously decrements S1. Decrementation may be optionally
terminated by manual adjustment of S1 (configurable by your distributor); in software versions 3.19.59
or earlier, decrementation was also paused by continuous press of the [Spacebar].

The RSYNCED_S2 protocol produces a train or a sequence of up to 3 extra-stimuli coupled to a train
