Therapy

• transvenous pacing ^a preferably using balloon-flotation catheters ^a  

Why?

• It is faster than using semirigid catheter (by roughly 4 minutes) and the catheter is more likely to be in a satisfactory position. ^a

Balloon flotation catheters are easier to place correctly than semirigid catheters

Patient	Treatment	Comparison	Outcome	CER	RRR (95% CI)	NNT (95% CI)
requiring temporary ventricular-demand pacing a	balloon-flotation catheters	semirigid catheter	satisfactory catheter position	10%	600% (82% to 2600%)	2 (1 to 3)

• There is no clear benefit from antibiotic prophylaxis. ^d
