Age

18 Years to No maximum

Inclusion criteria

Inclusion criteria: Typical (CTI dependent) atrial flutter documented in a standard 12 lead surface ECG with given class I indication for curative CTI ablation according to the current guidelines

Exclusion criteria

Exclusion criteria: previous isthmus ablation, tricuspid valve replacement, bidirectional conduction block not assessable, pregnant or breastfeeding women, abuse of alcohol or drugs

Design outcomes

Primary

Measure	Time frame
cumulative ablation duration to bidirectional conduction block	—

Secondary

Measure	Time frame
- applicated radiofrequency energy to bidirectional conduction block [kJ]; - procedure duration (sheath placement to its removal) [min]; - Efficacy dependent on anatomical factors, such as length and morphology of the CTI; - Efficacy dependent on concomitant diseases, such as diabetes and adiposis; - safety: adverse events; - use of radiation, fluoroscopy time [s], dose area product [cGy*cm^2];	—
