a Surface and endocardial ECG; CS panel showing atrial (1/2–9/10) and ventricular (1/2–7/8) potentials; His panel showing His (7/8, 9/10) and ventricular potentials (1/2–9/10); ablation catheter panel showing slow pathway potentials (black arrows); jagged isoelectric line (Abl 1/2) indicates ongoing cryo-mapping. b Cryo-mapping at the inferior triangle of Koch (ECG reveals uncompromised AV conduction) c Cryoadhesion during midseptal cryo-ablation - tenting of the septal tricuspid valve leaflet (entrapped by ice formation around the tip of the ablation catheter); distance to the His/RV diagnostic catheter on the right can be evaluated (ECG reveals uncompromised AV conduction)
