Role of advanced mapping systems based on arrhythmia
| Limited role for advanced mapping (high conventional success rate) | Advanced mapping shortens procedure, limits fluoroscopy, or enhances success | Advanced mapping extremely helpful or essential |
|---|---|---|
| AVNRT, atriventricular nodal re-entrant tachycardia; LVOT, left ventricular outflow tract; RVOT, right ventricular outflow tract, VT, ventricular tachycardia. | ||
| AVNRT | Typical atrial flutter | Macroreentrant atrial arrhythmias after surgical correction of congenital heart disease |
| Accessory pathway ablation | Idiopathic ventricular tachycardia (RVOT, LVOT, fascicular VT) | Transient/multiple focal atrial tachycardias |
| AV junction ablation (for rate control in atrial fibrillation) | Repeat ablation after previously failed attempt | Haemodynamically unstable VT |
| Haemodynamically stable VT (non-idiopathic) | Atrial fibrillation: linear lesions for atrial compartmentalisation procedures; also useful, but role less defined for encircling pulmonary vein isolation and non-pulmonary vein focus localisation | |
