Objectives

Narrative objectives1

Conventional pacemakers have been implanted with the right atrial lead in the right atrial appendage and the right ventricular lead in the apex. However, with the use of delivery catheters and intraoperative 12-lead ECGs, right ventricular leads can now be safely placed from the apex into the right ventricular septum and stimulating conduction system, and have been shown to be effective. Previous studies have shown that right atrial leads placed in the right atrial septum can shorten interatrial conduction time, which has been expected to reduce atrial fibrillation, but the results have been controversial.1) The reason for this result may be due to the lack of use of delivery catheters and intraoperative ECGs. We have shown in a retrospective study that pacemaker implantation using Medtronic's delivery catheter to place an atrial lead in the atrial septum in patients with sick sinus syndrome is safe and potentially effective in reducing atrial fibrillation.2) However, prospective randomized studies are needed to further build high-quality evidence.

Assessment

Primary outcomes

Safety: threshold, wave height, resistance, and complication rates including lead dislodgement
Effectiveness: P-wave width (interatrial conduction time) at induction II, atrial fibrillation duration, AT/AF rate

Key secondary outcomes

Safety: Tip position of atrial lead (confirmed by simple CT)
Effectiveness: Echocardiographic data (left atrial diameter, left atrial volume, left ventricular ejection fraction), blood sample data (NT-proBNP)
