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.

Why does amylase from saliva stop working in the stomach? what other organ produces amylase?
Novosadov [1.4K]
Amylase is an enzyme, which are protein molecules that help in the breakdown of complex substances. Enzymes have optimum conditions in which they operate, which also include specific pH ranges. The pH in the stomach is too low for amylase to work in, so amylase is denatured and does not perform its function in the stomach.

The other organ producing amylase is the pancreas.
