Can cardiac arrest heal itself?

Cardiac arrest is usually not self-healing.

Cardiac arrest refers to the effective contraction of the heart and sudden cessation of blood pumping function, which can lead to systemic blood circulation interruption. If this symptom does not occur in time, it may cause systemic ischemia, hypoxia, and severe shock.

After cardiac arrest, artificial chest compression and airway opening should be taken in time to restore the patient's heart beat and breathing to improve the prognosis. After waking, patients should also stay in bed and keep warm.
