Hurrah! Its time for pacing maneuvers

OMG! How to stop it?

Nice signal for relaxed ablation

Do not overlook critical warnings

Try your first entrainment

Is this the right signal to ablate?

Find the gap or go home

Are we done? AKA How to verify the block?

Where should I look?

That’s the spot to ablate

Are you sure you have entrance and exit block?

Two ways to find the gap in isolation

Find and destroy AKA pace and ablate approach

Try to spot isolated PV-potentials

Local capture and we can go home

The best filing in the world: termination by ablation

Finding the sweet spot

Try your first pace mapping

"Strange” respond to usual pacing maneuvers

This way or the other way around: antidromic or orthodromic
