In which dysrhythmias should treatment be instituted immediately? a. premature atrial complexes occurring every 20 seconds b. fever-induced tachycardia at 122 beats/minute c. asymptomatic sinus bradycardia at a heart rate of 50 beats/minute d. atrial fibrillation with a ventricular rate of 220 beats/minute

The answer is D: Atrial fibrillation with a ventricular rate of 220 beats/minute

Explanation:

Atrial fibrillation with a rapid ventricular response, is considered a medical emergency, since it is producing a poor tissue perfusion and the patient can enter a myocardial infarction, myocardial rupture or any other complication that put at risk of death, the life of this person.
