If your heart stops pumping blood, it would lead to cardiac arrest, causing immediate and severe consequences. Without blood flow, organs and tissues would quickly be deprived of oxygen, leading to unconsciousness within seconds and potentially permanent brain damage within minutes. Vital organs would begin to fail, resulting in a loss of consciousness and, ultimately, death if circulation is not restored promptly. This critical situation highlights the heart’s essential role in sustaining life, as immediate medical intervention is necessary to prevent irreversible damage and ensure survival.
