In brief: Can slow or increase
Standing up quickly causes blood to pool in the legs and causes the blood pressure to drop transiently.
How transient depends on how compensated a person is. If dehydrated, elderly, anemic, or diabetic, then the blood pressure can remain depressed and will actually lead to a fast heart rate. The only time that the hr would slow would be if the vagus nerve got activated - vasovagal response.
