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
The main function of the thalamus is to process information to and from the spinal cord and the cerebellum. The medulla oblongata helps regulate breathing, heart and blood vessel function, digestion, sneezing, and swallowing. This part of the brain is a center for respiration and circulation.Sensory and motor neurons (nerve cells) from the forebrain and midbrain travel through the medulla.edulla oblongata. The medulla oblongata is located in the brain stem, anterior to (in front of) the cerebellum. This is a cone-shaped, neuronal (nerve cell) mass in the hindbrain, which controls a number of autonomic (involuntary) functions.
