Why the study?
Does right atrial appendage pacing with prolonged P wave duration increase atrial fibrillation recurrence in patients with sick sinus syndrome?
Does right atrial appendage pacing with prolonged P wave duration increase atrial fibrillation recurrence in patients with sick sinus syndrome?
In patients with sick sinus syndrome undergoing right atrial appendage pacing, a prolonged paced P wave (>130 ms) is strongly associated with atrial fibrillation recurrence.
No takes yet. Share an insight, caveat, or question.
Prolonged paced P wave associated with higher AF recurrence; leaves open whether P-wave modification reduces events in sick sinus syndrome.
Endoh et al. (2003) studied this question.
