Arrhythmias & electrophysiologyCohort study
Redo procedures after sinus node sparing hybrid ablation for inappropriate sinus tachycardia/postural orthostatic sinus tachycardia
- Prospective registry study
- single-centre
- consecutive patients
Authors' conclusion
In a large cohort of patients the long-term free survival from redo procedure after hybrid IST ablation was 84.6% with a low PM implantation rate.
