How Good Is The US "Hulk" Blu-Ray?

It was more about that adrenaline (Epinephrine) was what caused him to change into the Hulk.

The hormone boosts the supply of oxygen and glucose to the brain and muscles, while suppressing other non-emergency bodily processes (digestion in particular). It increases heart rate and stroke volume, dilates the pupils, and constricts arterioles in the skin and gastrointestinal tract while dilating arterioles in skeletal muscles. It elevates the blood sugar level by increasing catabolism of glycogen to glucose in the liver, and at the same time begins the breakdown of lipids in fat cells. Like some other stress hormones, epinephrine has a suppressive effect on the immune system. Although epinephrine does not have any psychoactive effects, stress or arousal also releases norepinephrine in the brain. Norepinephrine has similar actions in the body, but is also psychoactive.

He most likely was using the heart monitor as a means of detecting how much adrenaline his body was currently producing.

More excited/worked up -> leads to higher adrenaline -> leads to higher heart rate.
Thus, if his heart rate were to increase, Banner would want to calm himself to slow the production of adrenaline in his body. Our bodies produce adrenaline at all times, but increase production in stressfull situations (anger, extreme excitement, fear). There would most likely be a set level of production that would cause him to transform into the Hulk.

The mistake that the movie made was that it portrayed an automatic transformation when Banner's heart rate hit 200 beats per minute. It most likely would not be an exact number, and would vary slightly from transformation to transformation (would probably stay within a 0-15 beat per minute range). It also did not explain the connections between adrenaline and heart beat, leaving the viewer to have to make that connection on their own.

did you really just analyze it that much
