Technical Data

RA
Right atrium
RAESW
Right atrial extrasystole safety window
Rate fading
Rate smoothing. If the rate suddenly drops, e.g., upon the onset of
bradycardia after a higher intrinsic rate.
RV
Right ventricle
Sense
Sensed event
SMS
Short messages via cellular phone (short message service)
SW
Safety interval (safety window)
Triggering
Forwarding and triggering of an action
ULAS
Left atrial sensing not used for timing the pacemaker (u = unused)
UTI/UTR
Upper rate limit (upper tracking rate/interval)
VES
Ventricular extrasystole (synonym: PVC = premature ventricular
contraction)
VES lock-in
By definition, an atrial event that occurs during the atrial refractory
period will not start a new basic interval.
VV
Interventricular conduction time
