Classification of asymptomatic accessory pathways based on risk of procedure and risk of life-threatening arrhythmias
| High-risk AP | Low-risk AP | |
| High-risk ablation | Careful discussion of arrhythmic and procedural risks; cautious attempt at ablation is generally reasonable. | Risk:benefit ratio likely favours observation. |
| Low-risk ablation | Risk:benefit ratio likely favours ablation. | Careful discussion considering arrhythmic and procedural risks; observation is generally reasonable. |
AP, atrioventricular pathway.
