The expression is a trinomial, like the expressions which we've been factoring in this lesson. There is a small variation in this problem however -- the first term has a coefficient that is not 1.
Ventricular Phonation (Plica Ventricularis). This occurs when a great amount of muscle tension above the vocal folds is created in the laryngeal area causing an approximation of the false vocal folds.entricular Phonation (Plica Ventricularis).

After the QRS complex, we see another small peak, and this is called the T wave. The T wave represents the repolarization of the ventricles. We know that repolarization is the opposite of depolarization and refers to the change of the membrane potential that returns the membrane back to a negative value.
