	Number of Treatments	Dose of Verapamil	Percent Change of MAP at 10 Min*;	Percent Change of MAP at 20 Min*	Percent Change of Heart Rate at 10 Min†	Percent Change of Heart Rate at 20 Mi†
Not on vasopressor	11	3.4 ± 0.5 mg (51 ± 9 mcg/kg	− 3.1 ± 1.5	− 0.6 ± 1.7	2.4 ± 2.3	4.0 ± 2.6
On vasopressor	23	3.0 ± 0.4 (42 ± 6 mcg/kg)	− 4.1 ± 1.3	− 2.2 ± 1.4	1.0 ± 1.2	1.0 ± 1.6

^*The baseline mean arterial pressure of these patients was 112 ± 3 mm Hg †(mean ± standard error of the mean).

^†The average pretreatment heart rate was 79 ± 3 bpm. (mean ± standard error of the mean).
