Table 3: Consensus Panel Recommendations on Preferred Pacemaker Implantation Access, Pacing Modes and Ventricular Lead Placement in Paediatric Patients With AV Block, Systemic LV and Absence of Intracardiac Shunts.

Patient Size	Access	Pacing Mode	Ventricular Lead Placement
<10 kg	Epicardial	VVIR or DDD(R)a	LV apex
	Endocardial-in specific situations (failed epicardial, centre preference)	VVIR or DDD(R)a	RV septum
10–20 kg	Epicardial	VVIR or DDD(R)a	LV apex
	Endocardial	VVIR or DDD(R)a	RV septum
>20 kg	Epicardial-specific situations (e.g. concomitant with other cardiac surgery)	VVIR or DDD(R)	LV apex or free wall- based on surgical feasibility
	Endocardial	VVIR or DDD(R)	RV septum
