  • (D) Immediately begin CPR, followed by defibrillation at 200 J, then 300 J, then 360 J

11 >>The patient in Question eventually develops a sinus rhythm with a stable blood pressure. He is transferred to the intensive care unit. It is discovered that the etiology of his ventricular fibrillation is most likely associated with a large anterior wall and myocardial infarction. During his postinfarction recovery phase, the patient undergoes a percutaneous coronary angioplasty with a stent placement; he quickly stabilizes. The patient has no further chest pain and no further arrhythmias during his hospitalization. Which of the following would be the most appropriate management decision with respect to his arrhythmia? ?

  • (A) No antiarrhythmia therapy is required
  • (B) An implantable cardioverter-defibrillator (ICD)
  • (C) Beta blocker
