The right answer is Electrocardiography (or Electrocardiogram).
In a typical plot, one can notice five characteristic waves. They are called P, Q, R, S and T. The illustration below shows what a normal electrocardiogram looks like:
* the P wave marks the depolarization during the contraction of the atria;
* the PR interval indicates the time required to transmit the electrical impulse of the sinus node of the atria to the ventricular muscles;
* the QRS complex marks depolarization and ventricular contraction;
* the QT interval corresponds to the global ventricular repolarization;
* T wave refers to the end of ventricular repolarization.

Answer:Pee is a funny little substance. It actually has lots of good stuff in it. Stuff you can’t live without in many cases – things like potassium and sodium and water. Your body, and more specifically, your kidneys, sense and adjust the composition of your bodily fluids and dump the excess into the urine. Just ate a super-sized order of fries with an ocean’s worth of sodium in it? Here come the kidneys to say ‘hold the salt’ and dump the unwanted excess into the urine. Ditto with lots of other substances, like water, that need to be regulated. And pee is (usually) sterile – unless you have a urinary tract infection (UTI) pee is pure enough that you could clean your windows with it. I’m not advocating doing anything crazy with it (except maybe writing your name in the snow), but it’s not the heinous grody stuff that many third graders make it out to be. True, it does have the waste products of metabolism in it, which your body definitely needs to get rid of.
