10) A 60-year-old patient with persistent atrial fibrillation is scheduled for electrical cardioversion. The patient has been anticoagulated appropriately. What is the primary goal of electrical cardioversion in this setting?

1 point

a. Symptomatic relief

b. Prevention of stroke

c. Rate control

d. Maintenance of normal sinus rhythm

e. Reduction of blood pressure

Clear selection

11) A 28-year-old man presented to the emergency department with palpitations after an electrical injury accident from a live wire carrying 220 volts in his home. He had loss of consciousness for 2 minutes after the accident but was conscious at admission. He had no history of cardiovascular disease. Blood pressure was 130/80 mmHg, heart rate was 150 beats/min irregularly irregular, respiratory rate was 20 breaths/min, body temperature was 36.6oc, and oxygen saturation was 98% on room air. ECG showed AF with rapid ventricular response at 150 - 200 beats/min. Laboratory tests and echocardiograms were in normal limits. What is the next step?

1 point

a. Admit for cardiac monitoring for 24 hours

b. Intravenous amiodarone

c. Heparin

d. Wait for self-conversion

Clear selection

12) A 55-year-old patient with symptomatic atrial fibrillation refractory to medical therapy is considering catheter ablation. What is the primary goal of catheter ablation in atrial fibrillation?

1 point

a. Immediate restoration of normal sinus rhythm

b. Prevention of stroke

c. Reduction of ventricular rate

d. Elimination of atrial fibrillation triggers

e. Anticoagulation therapy initiation

Clear selection

13) First-line therapy for rhythm control in with heart failure with reduced ejection fraction

1 point

a. Antiarrhythmic drug therapy

b. Catheter ablation

c. Left atrial appendage occlusion devices

d. Surgical ablation

Clear selection

14) True about vitamin K antagonists compared with non–vitamin K oral anticoagulants in patients who are aged ≥ 75 years and frail?

1 point

a. It reduced thromboembolic complications and bleeding complications

b. It reduced thromboembolic complications but increased bleeding complications

c. It increased bleeding complications without reducing thromboembolic complications

d. It was comparable for both thromboembolic complications and bleeding complications

Clear selection

15) True about dronedarone compared with sotalol in the maintenance of sinus rhythm in adults with AF

1 point

a. The drugs are comparable for AF recurrence or all-cause death

b. Dronedarone is associated with a lower risk for AF recurrence but no difference in all-cause death

c. Dronedarone is associated with a lower risk for all-cause death but no difference in AF recurrence

d. Dronedarone is associated with lower AF recurrence and all-cause death
