Among patients with cardiogenic shock, the rate of death was significantly higher in the group treated with dopamine than in the group treated with norepinephrine, although one might expect that cardiac output would be better maintained with dopamine26-28 than with norepinephrine. The exact cause of the increased mortality cannot be determined, but the early difference in the rate of death suggests that the higher heart rate with dopamine may have contributed to the occurrence of ischemic events. Whatever the mechanism may be, these data strongly challenge the current American College of Cardiology–American Heart Association guidelines, which recommend dopamine as the first-choice agent to increase arterial pressure among patients who have hypotension as a result of an acute myocardial infarction.7
i am 6 foot 2 inches tall, i am in the 8th grade, and i am 13 years old going on 14 in september. I discovered on May 15th that I could hang on the rim at my school with two hands by jogging about 3 steps very very slowly and jumping off both of my feet. I have dunked about 3 times before, but the last couple times I tried, I got "hung" and sent backwards but I managed to keep balance on the way down due to my height. What is my problem? Also after I attempt to dunk about 4 times in a day my shin begins to hurt. Why does this keep happening?
You will need to get at least that high to be able to snap the ball into the basket. If you're relatively short, then you have your work cut out for you. Developing a one-handed dunk requires less vertical ability than a two-handed dunk, and, for most players, jumping off of one foot from a running start makes it easier to jump high enough to dunk. There are many things that you can do to work on your vertical leap.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates.

Vertical jump measurements are used primarily in athletic circles to measure performance. The most common sports in which one's vertical jump is measured are track and field, netball, basketball, football, and volleyball, but many sports measure their players' vertical jumping ability during physical examinations. In addition, single and multiple vertical jumps are occasionally used to assess muscular strength and anaerobic power in athletes.[3]
