Pacing protocols
Burst pacing
Burst pacing involves pacing at a set rate for a certain amount of time.
​
Bursts nay be short (e.g., 3 beats) or may be long (e.g., 30 seconds)
​
This can be performed from either the atrium or the venticle on any catheter in the heart.​
​
This may be performed for many reasons
-tachycardia induction
-tachycardia termination
-to view activation patterns
-to provide a more stable heart rate for hemodynamic support
-to allow for consistent and faster 3D map collection
Decremental / incremental pacing
Pacing at a set rate, which is gradually increased (in bpm) or decreased (in ms) until a certain response is seen,
​
​​​Responses may include
-effective refractory period (ERP - unable to produce an evoked response)
-AV or VA block, including wenckebach
-tachycardia induction
​
This can be performed from either the atrium or the venticle on any catheter in the heart.
Pacing extra stimuli
Having a drive train of 8 beats at a set rate (S1 - stimulus 1), with an extra faster beat on the end (S2- stimulus 2).
​
This can be performed from either the atrium or the venticle on any catheter in the heart.
​
up to 3 extras can be added on to the end of the drive train (S3- stimulus 3 and S4- stimulus 4)
​
The last extra is usually decremented until a certain response is seen.
​
Responses may include
-effective refractory period (ERP - unable to produce an evoked response)
-AV or VA block, including wenckebach
-tachycardia induction
