Why the study?
Does heart rhythm change between sinus rhythm and atrial fibrillation affect the accuracy of left atrium registration during catheter ablation?
Does heart rhythm change between sinus rhythm and atrial fibrillation affect the accuracy of left atrium registration during catheter ablation?
Rhythm changes between sinus rhythm and atrial fibrillation do not introduce significant error to the left atrium registration process for catheter ablation, suggesting reregistration is unnecessary.
No takes yet. Share an insight, caveat, or question.
Rhythm at registration may not affect LA accuracy; leaves open whether reregistration is necessary.
Dong et al. (2007) studied this question.
