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).

Ventricular Ectopic Beats are also called premature ventricular contraction as they may occur just before the normal beat of the ventricle. Ventricular Ectopic beats also are common in people and they do not pose a risk unless there is a history of heart disease.
