Timing Events
The display of the event counter varies depending on the kind of
pacing. In addition to the graphic display, absolute values of the event
counter are displayed. The event counters are categorized into three
groups:
— All transitions
— Atrial sensing (A sense) and atrial pacing (A pace)
— V sense and V pace
The event counter can register the following events and event
sequences over a time period of several decades:
— Atrial sensing A
S
(outside the ARP)
—
Atrial pacing A
P
— Ventricular sensing V
S
(outside the VRP)
—
Ventricular pacing V
P
— Event sequences:

refractory sense events in the atrium
— V
RS
refractory sense events in the ventricle
The event sequence V—V means two consecutive ventricular events
(sensing or pacing) without a previous atrial event.

In this context, V - V means that all possible ventricular events can follow, such as
V
S
, V
P
and/or VES.
