Clinical trial	Patients in flecainide arm	AF duration	Formulation	Reversion rate
Capucci et al[38]	22 patients	≤ 7 d	Single oral dose (300 mg)	8 h → 91%
				24 h → 95%
Donovan et al[39]	51 patients	≤ 3 d	iv (2 mg/kg-max 150 mg)	1 h → 57%
				6 h → 67%
Donovan et al[40]	34 patients	≤ 3 d	iv (2 mg/kg-max 150 mg)	2 h → 59%
				8 h → 68%
Boriani et al[41]	69 patients	< 8 d	Single oral dose (300 mg)	1 h → 13%
				3 h → 57%
				8 h → 75%
Martínez-Marcos et al[42]	50 patients	≤ 2 d	iv (2 mg/kg followed by 1 mg/kg at 8 h if not SR)	1 h → 58%
				8 h → 82%
				12 h → 90%
Romano et al[43]	138 patients	≤ 3 d	Intravenous	1 h → 73%
				3 h → 80%
				6 h → 86%
				24 h → 90%
