Answer:
A) Being sad about friend moving
Explanation:
D) is loss of interest, a major depression symptom. Same with C) difficulty with concentrating. B) is very common with depression, as depression leads to eating disorders.
A) isn’t a huge thing. Sad isn’t the same as depressed. If the friend experiences B, C, and D for months after her friend moved, then she could be depressed. But so far, she’s not.
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.
