Cushings Triad-Hypertension, Bradycardia, Irregular Respirations

My questions:

1-What is the mechanism for Bradycardia if Sympathetic is discharging? (Epineph. is both Alpha + Beta Agonist!)

2-I read somewhere that Pulse Pressure also increases b/c as Systolic pressure increases Dyastolic decreases in this reaction. anyone knows why?
