Mode; Pacing; Pulse Amplitude; Pulse Width - Abbott Merlin PSA EX3100 Help Manual

Mode

The Mode parameter determines the stimulation and sensing method. The selected mode is in
effect at all times except during Burst Pacing (page 20). Details of each mode can be found in
Mode Descriptions (page 24).



Pacing

The Pacing parameter enables stimulation for the corresponding channel. For the Merlin™ PSA,
this parameter is linked to the Mode and V. Pacing parameters. See Pacing, Mode, and V. Pacing
Parameter Autoprogramming (page 16).

NOTE: Pacing. Stimulation applied during the PSA session is ONLY intended for use during
short-term lead evaluation tests and IS NOT intended for long term life-sustaining pacing
support.

Pulse Amplitude

The Pulse Amplitude parameter determines the voltage applied to the myocardium during the
stimulation pulse.

Parameter Settings and Availability (page 34)


Pulse Width

The Pulse Width parameter determines the duration of the pacing pulse applied to the
myocardium.



Refractory

The Refractory parameter determines the amount of time that the device is unresponsive to
signals following a sensed or paced event for the corresponding channel. The refractory period for
the corresponding channel is initiated by a sensed or paced event on that channel and either
ends when the period times out or is reset when another sensed or paced event occurs on that
channel.
In AAI Mode, the Refractory parameter determines the atrial refractory period. In dual-chamber
modes, the Refractory parameter determines the post-ventricular atrial refractory period.

S1S1

The S1S1 parameter determines the interval at which the Burst Pacing stimulation pulse is
applied.
