Electrophysiology Study/AF Induction Protocol

Stage		Stopping Rules
Stage 1	AV Block Cycle Length	Met Primary End Point (protocol completed)
	AV Node ERP (S1: 600)
	Atrial ERP (S1: 600)
	AV Node ERP (S1: 450)
	Atrial ERP (S1: 450)
Stage 2	15-beat Atrial Burst at 250ms	Met Primary End Point (protocol completed) OR Lost 1:1 atrial capture (proceed to Stage 3)
	15-beat Atrial Burst at 240ms
	15-beat Atrial Burst at 230ms
	15-beat Atrial Burst at 220ms
	15-beat Atrial Burst at 210ms
	15-beat Atrial Burst at 200ms
	15-beat Atrial Burst at 1900ms
	15-beat Atrial Burst at 180ms
Stage 3	#1 15-second^* Atrial Burst	Met Primary End Point (protocol completed)
	#2 15-second^* Atrial Burst
	#3 15-second^* Atrial Burst
	#4 15-second^* Atrial Burst
	#5 15-second^* Atrial Burst
End Protocol	No sustained AF/AT/AFL induced

The cycle length used for Stage 3 was the shortest cycle length (fastest pacing) that had 1:1 atrial conduction
