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: medications on admission: 1. metoprolol 25 mg po bid. 2. lipitor 20 mg po qd. 3. synthroid 0.88 mg po qd. 4. ambien 10 mg po q hs. 5. diazepam 5 mg po q hs. 6. multivitamin. 7. colace 100 mg po bid. 8. fish oil. allergies: aspirin, metal allergy. brief summary of hospital course: the patient was admitted on for an elective mitral valve replacement surgery. the patient underwent a minimally invasive mitral valve replacement via a right midaxillary thoracotomy. the patient's mitral valve was replaced with a #31 mm mosaic pericardial tissue valve. the procedure was performed by dr. , and he was assisted by dr. , and physician assistants, and . the crossclamp time was 262 minutes. the cardiac bypass time was 343 minutes. there were no complications during the procedure, and the patient tolerated the procedure without any incidents. following surgery, the patient was transferred to the pacu, and after a brief stay went to the csru on epinephrine, neo-synephrine, propofol drips. on postoperative day #1, the patient was extubated and was able to maintain her o2 saturations on small amounts of nasal cannula oxygen. from a cardiovascular standpoint, the patient was maintained on neo-synephrine for her blood pressure. her port-a-cath and swan lines were removed. her pacer was off, as it was not sensing or capturing appropriately. the patient had her chest tube removed on the first day. she tolerated this without any difficulty. on postoperative day #2, the patient continued to do very well. she was out of bed with assistance. the patient did have several episodes of rapid atrial fibrillation. external pacing was used, as her a-wires were unable to capture a rhythm appropriately. the patient had her pacer turned off, and she was able to convert into a sinus bradycardia rhythm. the patient was also seen by psychiatry on this date, as she was having high level of anxiety and paranoia. the patient was taken off of haloperidol and started on seroquel 100 mg in the morning and 50 mg in the evening. the patient was also seen by the electrophysiology service which had recommended an increase in beta blockers, and to avoid amiodarone. on , postoperative day #3, the patient was transferred to the surgical floor. the patient remained in normal sinus rhythm with occasional bursts of atrial tachycardia with the rates up to 160-170s. the patient rapidly converted to a normal sinus rhythm with low dose of iv lopressor. while on the floor, the patient was seen by physical therapy which recommended, after two sessions, that the patient would be able to be transferred to an extended care facility. following her transfer to the floor, the patient continued her course in an unremarkable fashion. the patient did have several episodes of rapid atrial tachycardia. during these episodes, the patient states that she would occasionally feel lightheaded, but denied any chest pain, shortness of breath, arm pain, nausea, vomiting. the patient said her only complaint was that she would feel her heart racing. the patient would quickly revert to a normal sinus rhythm after administration of 2.5-5 mg iv lopressor. the patient had been followed closely by electrophysiology. the recommendations from ep are to continue the patient's beta blocking, but not to use amiodarone, as the patient was not in atrial fibrillation. follow-up to psychiatry note: the patient was increased on her seroquel to 100 mg with the recommendation to increase her seroquel 50 mg after about 3 days, and again 50 mg in another 4 days. psychiatry wishes to maintain her on 200 mg po bid of seroquel. psychiatry also recommended starting low dose clonazepam at 0.25 mg po tid. over the next couple of days, the patient continued to get stronger and was able to tolerate her regular diet without any difficulty. the patient continued to have supraventricular tachycardia approximately one time a day with her heart rate getting into the 190s. fortunately, these were able to be converted quickly with iv lopressor. on , after a period of over 24 hours without any ventricular ectopy, or supraventricular tachycardia, it was determined by both the patient and the medical team that the patient would be ready to be discharged to an extended care facility. prior to her discharge, the patient did have a tte performed. results of the tte were still pending. after discharge, the patient will be sent to center for further cardiac rehab. discharge disposition: the patient will be discharged to center. follow-up: 1. the patient was instructed to follow-up with her primary care physician, . in weeks. 2. the patient was asked to follow-up with her cardiologist, dr. , in weeks. 3. the patient was additionally instructed to follow-up with dr. in 4 weeks. please advise to contact these physicians to schedule the appointments. discharge condition: good: afebrile, in normal sinus rhythm, pain well-controlled on oral medications, ambulating without assistance but still weak. discharge examination: t-max 98.4, pulse 84 and sinus, blood pressure 118/60, breathing 96% on 2 liters. laboratory: blood count 6.2, hematocrit 29.2, platelets 334, sodium
