- Assessment of VT mechanisms in Brugada Syndrome and ARVC
- Assessment of ECG-i mapping system, EC-VUE (Medtronic) in VT and AF ablation


Mechanisms and ablation of atrial arrhythmias

- Mechanistic studies of characteristics of macro-entrant ATs
- Assessment of novel algorithms for Carto (Coherence) and Ensite Precision (HD Grid)
- Assessment of AF mapping technology: Acumap (Acutus), Constellation (Boston Scientific), FIRM (Topera), Cartofinder (Biosense)
- Outcome of persistent AF ablation


Inherited Cardiac Conditions

- Outcomes following S-ICD implantation
- Assessment of isoproterenol testing in ARVC
- Multi-national study of risk stratification in Brugada Syndrome
