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).

PVCs refer to early depolarizations commencing in the ventricle instead of the sinus node. Ventriculartrigeminy is defined as the occurrence of a PVC every third beat. A high frequency of trigeminy PVCs in heart disease patients has been found to cause ventricular fibrillation and unexpected death.
