AF prevention therapies

Vitatron introduced the first cardiac stimulator designed to prevent the onset of atrial arrhythmias in 1999, the Selection series. These, and subsequent generations of cardiac stimulators, introduce dedicated therapies to stop AF from starting by suppressing the underlying onset mechanisms.
Vitatron's unique beat-to-beat atrial rhythm monitoring ensures instant recognition of irregularities. It immediately applies a dedicated therapies designed to suppress AF onsets.

Clinically, for patients suffering from bradycardia and AF, the AF prevention pacing therapies can:

• Promote and maintain a normal sinus rhythm
• Improve hemodynamics
• Reduce the risk of stroke
• Improve the quality of life

Vitatron offers four AF prevention pacing therapies for triggered overdrive pacing which react to onset triggers of AF.Vitatron’s unique Beat-to-Beat monitoring ensures instant recognition of irregularities in atrial rhythm and immediately applies one of four dedicated algorithms designed to stop AF from starting. In addition there are two more AF prevention pacing therapies for continuous overdrive pacing which aim to condition the atrial activation pattern by dynamically overdriving the atrial rate.

Triggered overdrive pacing:

Post-Exercise Response™ (1,2)


Objective:
Limit the rate deceleration during recovery.


Method:
The post-exercise intervention rate slowly drifts upward until just below the underlying intrinsic rate, and limits rate deceleration during recovery.

top

PAC Suppression™ (1,2)


Objective:
Suppress PACs by an elevated rate.


Method:
Increase the rate upon PAC detection for a certain period.

top

Post-PAC Response™ (1,2)


Objective:
Eliminate post PAC pauses.


Method:
Shorten the escape interval for one beat after a PAC.

top

Post AF Response (1)

Objective:
Prevent recurrences of AF immediately after cessation of a preceding AF episode.

Method:
Increase pacing rate for a certain period after an AF episode.
