Table 1.

Group median durations (seconds) of Q-T, R-R, and corrected Q-T (Q-Tc) intervals measured in animals with right stellate ganglionectomy (RSGX), sham (SHAM) operated control animals, and time control (CON) animals.

TREATMENT GROUP	BASELINE			HYPOXIA
	R-R	Q-T	Q-Tc	R-R	Q-T	Q-Tc
RSGX	0.342*	0.191*	0.330*	0.288†	0.168†	0.313
SHAM	0.294	0.171	0.313	0.267†	0.160†	0.309
CON	0.317	0.171	0.304

*Interval durations of RSGX animals at baseline were significantly longer than those of either SHAM or CON groups.

†Within groups comparisons of interval durations, baseline vs. hypoxia, showed significant decreases in durations during hypoxia in RSGX and SHAM animals.
