Baseline intracardiac conduction intervals in 3-month-old mice

	SNRT (ms)	AVNERP (ms)	AERP (ms)	AV WB (ms)	VERP (ms)
WT (n = 9)	98 ± 50	52 ± 6	34 ± 2	90 ± 7	43 ± 9
SK3+/T (n = 13)	88 ± 48	50 ± 9	36 ± 4	81 ± 10	38 ± 6
SK3T/T (n = 3)	124 ± 52	61 ± 1	34 ± 6	88 ± 2	38 ± 2

Measurements of refractory periods were made using a basic cycle length of 100 ms. Data are expressed as mean ± standard deviation.

SNRT, sinus node recovery time; AVNERP, atrioventricular nodal effective refractory period; AERP, atrial effective refractory period; AV WB, atrioventricular Wenckebach cycle length; VERP, ventricular effective refractory period.
