Ventricular Tachycardia is characterized by a rapid rate of ventricular contractions, which typically occurs at a heart rate exceeding 100 beats per minute. This condition arises from abnormal electrical activity in the ventricles and can lead to reduced cardiac output and potentially collapse or ventricular fibrillation. The rapid contractions can significantly impact the heart's ability to pump blood effectively, causing symptoms such as palpitations, dizziness, or even loss of consciousness.

Each of the other options describes different cardiac phenomena that are not representative of Ventricular Tachycardia. A slow heartbeat refers to bradycardia, an absence of electrical impulses can denote asystole or severe conduction blocks, and a regular rhythm of the atria reflects atrial activity rather than ventricular functions. These distinctions are crucial in understanding the various cardiac conditions and their implications for patient care.
