Table 3

Comparisons of thyroid hormones in patients before and after WK^* or sotalol treatments in the first investigation.

Before treatments

FT3^* (pmol/L)	24.613 ± 5.059	24.405 ± 5.006	−0.278 (0.781)
FT4^* (pmol/L)	118.697 ± 29.213	116.132 ± 28.266	−0.598 (0.550)
TSH^* (IU/mL)	0.007 ± 0.010	0.009 ± 0.147	1.191 (0.235)
Three months after treatments
	WK^* treatment (91 cases)	Sotalol treatment (89 cases)	value ( value)^**
FT3^* (pmol/L)	6.495 ± 3.713	6.596 ± 3.740	0.182 (0.855)
FT4^* (pmol/L)	21.447 ± 11.727	21.655 ± 10.612	0.125 (0.901)
