Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: allergies: penicillins attending: chief complaint: palpitations major surgical or invasive procedure: s/p dc - cardioversion on history of present illness: in brief, 45 yo woman with history of svt (long r-p) followed for 5 years, episodes monthly, usually lasting > 1 hr with recent ed presentation for new afib. she was symptomatic with palpitations and shortness of breath with the afib. she underwent dccv last week and discharged home on asa with outpatient echo and ep study scheduled for and , respectively. given h/o svt there is a possibility that the svt may have triggered af. she now presents with recurrent afib with dyspnea and mild chest tightness. no fevers. in ed she was in afib with hr 110-120, bp in 70's. past medical history: svt afib ? marfan's syndrome left upper extremity radiculopathy polypectomies dilatation curettage difficulty with conceive a pregnancy social history: lives at home. has three year old son. tobacco, ivdu. family history: mother with syndrome -

recent cardioversion for afib, now returns with recurrence. rate is fairly well controlled. thyroid studies wnl. patient underwent dc cardioversion, but had recurrent atrial fibrillation post-procedure. she was started on flecainide after attempt at cardioversion with low dose beta-blocker. she converted back into sinus rhythm that same night. she was discharged on flecainide 50mg po bid and metoprolol. she is to scheduled outpatient exercise (non-imaging) stress test in one week after discharge from the hospital. she has outpatient follow-up for possible ep study with dr. in the next couple of weeks. she was discharged with of hearts monitor. she had tte echo with mitral regurgitation and prolapse and was instructed to take pre-procedure antibiotics for any dentalwork. pcn allergy so given prescription for clindamycin. . # dyspnea - most likely related to afib, and resolved on admission after bring her heart rate down. no evidence of pulmonary edema or infiltrate on cxr. d-dimer negative. no jvd, and bedside echo in ed without pericardial effusion. breathing comfortably on room air throughout hospitalization. . # dispo -
