1

effects of adenosine

incr. hrt. rate by 15bpm BP reduced by 10% low grade AV blocks

2

Adenosine

increases Coronary blood flow 4-6 times over baseline side effects are short lived

3

affects of the dipyridamole

20% incrs. hrt rate over baseline 10 mmHg fall in BP effects more pronounced in patients who develop ST depression

13

vasodilator agents

acts by blocking cellular uptake and inhibiting adenosine breakdown
