What the complete stopage of the heart called?

The complete stoppage of the heart is called cardiac arrest. During cardiac arrest, the heart ceases to pump blood effectively, leading to a loss of consciousness and cessation of breathing. This condition is a medical emergency that requires immediate intervention, such as cardiopulmonary resuscitation (CPR) and defibrillation, to restore normal heart function. If not treated promptly, cardiac arrest can result in death within minutes.
