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: patient recorded as having no known allergies to drugs attending: chief complaint: atrial fibrillation major surgical or invasive procedure: atrial fibrillation ablation cardioversion history of present illness: mr. is a 48 yo male with a history of chronic atrial fibrillation who is transferred to the ccu s/p pulmonary vein isolation with successful ablation procedure. course was complicated by post-procedure hypotension with sbp 90. patient was mentating and asymptomatic. he was started on a dopamine drip and paced at hr 70 with atrial lead due to severe sinus node bradycardia. . on review of symptoms, he denies any prior history of stroke, tia, deep venous thrombosis, pulmonary embolism, bleeding at the time of surgery, myalgias, joint pains, cough, hemoptysis, black stools or red stools. he denies recent fevers, chills or rigors. he denies exertional buttock or calf pain. all of the other review of systems were negative. . post-procedure he complained of low back pain and palpitations consistent with arrhythmia detected on telemetry. cardiac review of systems is notable for absence of chest pain, dyspnea on exertion, paroxysmal nocturnal dyspnea, orthopnea, ankle edema, syncope or presyncope. past medical history: 1. persistent chronic atrial fibrillation: patient has a history of chronic atrial fibrillation diagnosed approximately 11 years ago. he was initially diagnosed after developing dizziness, palpitations and presyncope while playing basketball. he has been treated with both amiodorone and sotalol in the past, without success. of note, the patient has never taken coumadin and has never undergone cardioversion. he reports being persistently in atrial fibrillation for at least the past five years. he recently underwent echocardiogram at an osh which demonstrated an ef of 40%. he subsequently underwent cardiac catheterization at hospital which revealed normal coronary arteries. he was referred in for ep consultation with dr. to discuss options for treatment of his atrial fibrillation. 2. cardiomyopathy-ef 45% 3. right arthroscopic shoulder surgery 4. tonsillectomy social history: he is married with four children. he does not smoke. he drinks alcohol on occasion and occasionally smokes marijuana. he is an avid basketball player. he works for fidelity investment. family history: there is no family history of premature coronary artery disease or sudden death. there is no family history atrial fibrillation, diabetes, or hypertension. his paternal grandfather died of a myocardial infarction. physical exam: vs: bp 111/63 on dopa gtt @ 5 mcg/kg/min, hr 65, rr 14, o2 96% on ra gen: wdwn middle aged male in nad, resp or otherwise. oriented x3. mood, affect appropriate. pleasant. heent: ncat. sclera anicteric. perrl, eomi. conjunctiva were pink, no pallor or cyanosis of the oral mucosa. neck: supple with jvp of 7 cm. cv: regular rhythm, pmi located in 5th intercostal space, midclavicular line. rr, normal s1, s2. no s4, no s3. chest: no chest wall deformities, scoliosis or kyphosis. resp were unlabored, no accessory muscle use. no crackles, wheeze, rhonchi. abd: obese, soft, ntnd, no hsm or tenderness. no abdominial bruits. ext: no c/c/e. no femoral bruits. skin: no stasis dermatitis, ulcers, scars, or xanthomas. pulses: right: carotid 2+ without bruit; femoral 2+ without bruit; 2+ dp left: carotid 2+ without bruit; femoral 2+ without bruit; 2+ dp pertinent results: 07:45am glucose-92 urea n-26* creat-1.2 sodium-141 potassium-4.1 chloride-105 total co2-25 anion gap-15 07:45am estgfr-using this 07:45am wbc-4.6 rbc-4.25* hgb-13.9* hct-39.0* mcv-92 mch-32.8* mchc-35.7* rdw-13.6 07:45am plt count-207 07:45am pt-13.3 ptt-25.4 inr(pt)-1.1 echo (): the left atrium is dilated. no spontaneous echo contrast is seen in the body of the left atrium or left atrial appendage. no mass/thrombus is seen in the left atrium or left atrial appendage. mild spontaneous echo contrast is seen in the body of the right atrium. the right atrial appendage ejection velocity is depressed (<0.2m/s). no atrial septal defect is seen by 2d or color doppler. overall left ventricular systolic function is mildly depressed. the aortic valve leaflets (3) appear structurally normal with good leaflet excursion. no masses or vegetations are seen on the aortic valve. no aortic regurgitation is seen. the mitral valve appears structurally normal with trivial mitral regurgitation. no mass or vegetation is seen on the mitral valve. there is no pericardial effusion. impression: no intracardiac thrombus identified. brief hospital course: mr. is a 48 yo male with chronic atrial fibrillation who was admitted to the ccu s/p successful ablation procedure, complicated by hypotension, who was subsequently weaned off dopamine drip and reverted back to atrial fibrillation. the patient was then electively electrically cardioverted and was discharged to home. . # rhythm: patient converted back to atrial fibrillation after electrical cardioversion subsequent to failed ablation procedure, was summarily given anticoagulation after the procedure . # hypotension: patient was weaned off of dopamine drip, and progressed with bp's in 120's/60's, was restarted on his beta blocker and his ace-i. . # pump: patient was shown to have an ef 45%. a tte here revealed a dilated left atrium, reflecting structural changes due to chronic arrhythmia. medications on admission: metoprolol 100mg daily lisinopril 5mg daily aspirin 325mg daily discharge medications: 1. outpatient lab work please draw inr on sunday and call results to dr. : . please ask for the doctor on call. 2. quinidine gluconate 324 mg tablet sustained release sig: two (2) tablet sustained release po q8h (every 8 hours) as needed for af. disp:*100 tablet sustained release(s)* refills:*0* 3. enoxaparin 100 mg/ml syringe sig: one (1) syringe subcutaneous (2 times a day). disp:*10 syringe* refills:*1* 4. warfarin 2 mg tablet sig: three (3) tablet po once a day as needed for af ablation. disp:*60 tablet(s)* refills:*0* 5. quinidine gluconate 324 mg tablet sustained release sig: two (2) tablet sustained release po every eight (8) hours. disp:*140 tablet sustained release(s)* refills:*1* 6. aspirin 325 mg tablet sig: one (1) tablet po once a day. discharge disposition: home discharge diagnosis: atrial fibrillation discharge condition: stable. inr 1.2 . oumadin 5mg po , . coumadin 10 mg . qtc=.32 on discharge instructions: you had an atrial fibrillation ablation that did not successfully keep you in a normal rhythm. you then had a cardioversion that did change your rhythm into a normal sinus rhythm. you were started on quinidine gluconate to try to keep you in a normal rhythm. you will go home with of hearts monitor to track your rhythm at home. you are also going home on coumadin which is to prevent blood clots. written information was given to you and discussed with you about side effects, diet, drug interactions and when to call your doctor. you need to keep a coumadin blood level (or inr) between . until your coumadin level is > 2, you will need to take lovenox injections twice a day. dr. will tell you when to stop taking your lovenox. you need to take a full 325mg tablet of aspirin daily. please keep all of your follow-up appts. . call dr. of dr. if you have heavy bruising, dark or red stools, severe nosebleeds or any other signs of bleeding. also call your physician if you have palpitatations, dizziness, chest pain or nausea/vomiting. . dr. will follow your inr and tell you how much coumadin to take every day. please get your inr drawn at the hospital on sunday morning and have them call results to dr. . the covering physician will tell you how much coumadin to take on sunday. you had 5 mg of coumadin on and . this was increased to 10 mg coumadin on and . you should take 6 mg of coumadin on saturday , then wait to take your coumadin on sunday with dose as per dr. . followup instructions: provider: , md phone: date/time: monday at 4pm. dr. will follow inr and prescribe coumadin. cardiology: , md phone: date/time: wednesday at 3pm. please call dr. office next week to see if he would like to see you in the next month as well. procedure: catheter based invasive electrophysiologic testing excision or destruction of other lesion or tissue of heart, endovascular approach cardiac mapping diagnoses: other primary cardiomyopathies other iatrogenic hypotension atrial fibrillation other postprocedural status
