Table 2.

Effect of endocardial pacing vs. mid-myocardial pacing vs. epicardial pacing on T_M–Epi before and after ibutilide administration (n = 12).

	Endo pacing	Mid pacing	Epi pacing	P value
	Endo pacing	Mid pacing	Epi pacing	ANOVA	Endo vs. Mid	Mid vs. Epi	Epi vs. Endo
Before ibutilide	8.6 ± 1.1	9.0 ± 0.9	21.8 ± 2.1	< 0.001	0.552	< 0.001	< 0.001
After ibutilide	8.8 ± 0.8	8.4 ± 1.1	23.2 ± 2.2^⁎	< 0.001	0.561	< 0.001	< 0.001

Endo indicates endocardial; Mid, mid-myocardial; Epi, epicardial; and ANOVA, analysis of variance.

^⁎

P < 0.05 (vs. after ibutilide).
