Ventricular tachycardia. Ventricular tachycardia (V-tach or VT) is a type of regular and fast heart rate that arises from improper electrical activity in the ventricles of the heart. Although a few seconds may not result in problems, longer periods are dangerous. Short periods may occur without symptoms or present with lightheadedness, palpitations, or chest pain.
The midbrain tegmentum contains thousands of neurons that are responsible for a variety of many functions, two of which include the control of movement and sensory systems. See also
This region of the pons also contains the pontine nuclei, which give rise to the axons that transmit to the opposing cerebellar hemisphere, and do this via the middle cerebellar peduncle (via the transverse pontine fibres). Pontine Tegmentum-The posterior part of the pons is known as the tegmentum. The dorsal surface of this region forms the floor of the fourth ventricle. The superior cerebellar peduncle consists mainly of efferent fibers from the cerebellum to the thalamus.
