PVCs
If the pacemaker has been operating in a dual chamber mode, Event Sum-
mary displays the counted number of PVC “singles” and “runs.” A PVC
(premature ventricular contraction) is defined by the pacemaker as a ven-
tricular sense that follows a ventricular pace or sense without an intervening
atrial pace, atrial sense, or atrial refractory sense.
Singles
— Show the number of singly-occurring PVCs.
Runs
— Show the number of runs consisting of two or more PVCs.
A greater-than symbol (>) appearing in front of the displayed value indi-
cates memory for this data is full and data collection has stopped. Since
PVC data collection applies only to dual chamber modes, this feature will
not be displayed if a single chamber mode was in effect during the monitor-
ing period.
Mode Switch Episodes
“Mode Switch Episodes” is displayed in the Event Summary if the Mode
Switch parameter (see Chapter 14) applies to the pacing mode in effect
during the monitoring period.
If Mode Switch is programmed ON, the number of mode switch episodes
occurring during the monitoring period is displayed. If the number of
episodes exceeds the range maximum (255), data collection stops, and a
greater-than symbol (>) appears in front of the displayed value.
If Mode Switch is programmed OFF, the display shows “Off” in place of
a value.
