What is the initial priority for an unconscious patient with any tachycardia on the monitor?

The initial priority for an unconscious patient with tachycardia is to ensure their airway is secure and assess their breathing and circulation. Immediate interventions may include administering oxygen, establishing intravenous access, and monitoring vital signs. If the patient is unstable, advanced cardiac life support protocols may be initiated, including potential defibrillation if indicated. Rapid identification and treatment of the underlying cause of the tachycardia are also essential.
