Why does the heart rate slow down after standing up too fast?

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.
