What is the term for the accelerated beating of the heart during a seizure?

The term that refers to the accelerated beating of the heart during a seizure is tachycardia. This is a physiological response characterized by an increase in heart rate, which typically exceeds 100 beats per minute in adults. During a seizure, the body may experience heightened levels of stress and altered brain activity, leading to a fight-or-flight response, which can result in tachycardia as the body's way of ensuring that more blood and oxygen are delivered to vital organs and muscles during this intense event.

The other terms provided refer to different conditions: tachypnea pertains to an increased respiratory rate, cardialgia refers to heart pain or discomfort, and arrhythmia denotes an abnormal heart rhythm. These conditions do not accurately describe the specific phenomenon of a rapid heart rate that occurs during seizures, making tachycardia the correct and most relevant term in this context.
