A patient converts from normal sinus rhythm at $80 \mathrm{bpm}$ to atrial fibrillation with a ventricular response at $166 \mathrm{bpm}$. Blood pressure is $162 / 74 \mathrm{~mm} \mathrm{Hg}$. Respiratory rate is 20 breaths per minute with normal chest expansion and clear lungs bilaterally. IV heparin and Cardizem are given. The nurse caring for the patient understands that the main goal of treatment is what?

Question

Quizplus · Accepted Answer

Treatment for atrial fibrillation is to terminate the rhythm or to control ventricular rate. This is a priority because it directly affects cardiac output. A rapid ventricular response reduces the time for ventricular filling, resulting in a smaller stroke volume. Control of rhythm is the initial treatment of choice, followed by anticoagulation with heparin and then Coumadin.
