Therapy

• beta-blockers: e.g. esmolol, ^c nadolol ^a

Why?

• Esmolol is probably as effective as propranolol at cardioversion ^d
• Nadolol is more effective than placebo at slowing the ventricular rate and achieving cardioversion ^a

SVT: nadolol helps slow the ventricular rate and cardioversion

Patient	Treatment	Comparison	Outcome	CER	RRR (95% CI)	NNT (95% CI)
paroxysmal SVT a	nadolol	placebo	ventricular rate < 100, or sinus rhythm at minutes	20%	-59% (-88% to -29%)	2 (1 to 3)
