High-density electroanatomic activation mapping to guide slow pathway modification in patients with persistent left superior vena cava
Authors' conclusion
High-resolution activation mapping of the KT in sinus rhythm can facilitate localization and safe SP ablation in patients with PLSVC.
Study context
- Population
- Patients with PLSVC and dual atrioventricular (AV) nodal physiology undergoing slow pathway modification
- Participants
