Atrial Capture Management (ACM)
Device automatically monitors atrial pacing thresholds at periodic values. Once the threshold is determined, the device determines a target output based on the programmable safety margin and programmable minimum amplitude
Atrial Preference Pacing (APP)
Designed to maximize atrial pacing percentage to reduce the incidence of atrial tachyarrhythmias. When enabled, it can be programmed to provide continuous pacing that slightly exceeds the intrinsic sinus rate whenever the patient is not in an atrial tachyarrhythmia.
Atrial Rate Stabilization (ARS)
Programmable feature designed to prevent the long sinus pause that commonly follows a premature atrial contraction (PAC).
Conducted AF Response (CAFR)
Adjusts the ventricular pacing rate to help promote regularity within ventricular intervals during AT/AF episodes. It modifies the ventricular pacing rate to be faster when ventricular sensed events occur, and slower when ventricular pacing pulses occur during periods of AT/AF.
Managed Ventricular Pacing (MVP)
Promote intrinsic conduction by reducing unnecessary right ventricular pacing. These modes provide atrial-based pacing with ventricular backup. If AV conduction is lost, the device is designed to switch to DDDR or DDD mode. Periodic conduction checks are performed, and if AV conduction resumes, the device switches back to AAIR or AAI mode.
Non-Competitive Arial Pacing (NCAP)
Intended to prevent triggering of atrial tachycardias by delaying the scheduled atrial pace from occurring within the atrium’s relative refractory period.
Post Mode-Switch Overdrive Pacing (PMOP)
Works with the Mode Switch feature to deliver overdrive atrial pacing following an AT/AF episode termination. When the AT/AF episode has terminated, the device will pace at a programmed higher rate for a programmed period of time.
Rate Adaptive AV (RAAV)
In the normal heart, AV conduction times tend to shorten as the heart rate increases and to lengthen as the heart rate decreases. The Rate Adaptive AV (RAAV) feature mimics this physiologic response.
Rate Drop Response (RDR)
Intended to provide backup pacing and prevent associated symptoms in patients who experience occasional episodes of significant drop in heart rate
Rate Response (RR)
Adapts the pacing rate to changes in the patient’s physical activity. An activity sensor is used to measure the patient’s movement and to determine the appropriate pacing rate.
Ventricular Capture Management (VCM)
Monitors pacing thresholds at periodic intervals. Once the threshold is determined, the device determines a target output based on the programmable safety margin and programmable minimum amplitude.
Ventricular Rate Stabilization (VRS)
Designed to eliminate the long pause that commonly follows a premature ventricular contraction (PVC). VRS responds to a PVC by increasing the pacing rate, then gradually slowing it back to the programmed pacing rate or intrinsic rate.
Ventricular Safety Pacing (VSP)
Detects crosstalk by monitoring for non-physiologic ventricular sensed events and responds by pacing the ventricle.
