Initial treatment

Patient care.

Perform cardiopulmonary resuscitation (CPR) until the defibrillator is attached and functional.

Use the defibrillator according to the instructions.

Continue CPR when appropriate.

Next treatment

Consider the underlying cause of asystole cardiac arrest (electrical activity without impulses).

Always, minimize interruption of chest compressions, especially during IV placement.

Verify asystole arrest in 2 leads, if possible.

Review and treat underlying causes of asystole cardiac arrest.

If the cause is unknown and asystole arrest persists:

Epinephrine 1: 10,000 1 mg IV every 3-5 minutes; Vasopressin 40 units IV may be substituted for the first or second dose of epinephrine 1:10,000.

Complementary treatment

Additional doses of the above drugs.

Sodium Bicarbonate 1 mEq / kg vein.

Atropine 1 mg IV, repeated up to a maximum dose of 3 mg.

Possible causes
