👉 Hyperperistaltic, also known as hyperpolarization, is a physiological response that occurs when an electrical impulse or shock travels through the body and causes a significant increase in the electrical activity of muscle cells. This mechanism is named after the fact that it can cause the contraction of muscles to become more active than usual. In essence, this refers to a sudden increase in the rate of electrical activity within muscle cells, which can be associated with increased force production or an increase in heart rate.
