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: history of present illness: this is an 86 year old caucasian male with past medical history significant for hypertension and possible v-tach. he presented to an outside hospital with a syncopal episode. previously he had been in his usual state of health until one day prior to admission when he had a brief episode of lightheadedness. today while walking to the bedroom he syncopized for an unknown period of time. he denies preceding chest pain, lightheadedness, shortness of breath, nausea, vomiting, palpitations or diaphoresis. he felt well without confusion or loss of continence after the event. apparently he called his neighbor and came to the hospital and had one more episode of lightheadedness prior to arrival to the hospital. at showed complete heart block with ventricular wide complex, right bundle branch block, escape rhythm at 30 to 40 with some bigeminy. he was hemodynamically stable with blood pressure of 120/58 and was transferred to for further management. in the e.d. systolic blood pressure was between 130 to 140 with a heart rate of 30 to 40 with verifying the same. he was admitted to the ccu for further management. at the time of transfer he was without any symptoms. past medical history: left total hip replacement 14 years ago. status post appendectomy. hypertension. glaucoma. gout. chronic lower extremity edema. gerd. medications on admission: xalatan gtt., lopressor 50 mg p.o. b.i.d., prilosec 20 mg p.o. q.d., colchicine 0.6 mg q.o.d., lasix, timolol gtt., prazosin 5 mg b.i.d. allergies: penicillin, unknown reaction. social history: he is widowed three times. he lives alone. he denies tobacco use. he has occasional alcohol use. family history: noncontributory. laboratory data: on admission white blood cells were 8.6, hematocrit 37.2, platelets 133. chem-7 showed sodium of 139, potassium 4.6, chloride 103, bicarb 22, bun 38, creatinine 2.3, sugar 249. first cpk was 120 with troponin less than 0.3. inr was 0.8, ptt 31.5. at the outside hospital showed complete heart block with ventricular rate of 32, atrial rate of 75 with a wide escape complex which was at times bigeminal with right bundle branch morphology. there were no obvious ischemic changes. here showed atrial rate of 70, ventricular rate of 40 with right bundle branch morphology. physical examination: vitals were pulse of 36, respiratory rate 21, sating 99% in room air, blood pressure 180/59. in general, he was a pleasant, conversant, elderly male in no acute distress. heent: pupils equal, round and reactive to light. extraocular movements intact. oropharynx clear. mucous membranes dry. there was a right cheek fungulating growth. neck: jvd to earlobe, positive a waves, carotids 2+ without bruit. trachea midline. chest clear to auscultation bilaterally. cardiovascular bradycardic, s1, s2 normal, no murmurs, rubs or gallops. abdomen soft, nontender, nondistended, positive bowel sounds, no hepatosplenomegaly or masses. extremities had 3+ pitting edema unchanged from baseline, warm. neuro: alert and oriented times three, grossly nonfocal. hospital course: the patient was admitted to the ccu for further evaluation and observation. immediately on transfer to the ccu transvenous pacemaker was placed by right ij approach. he began to be ventricularly paced at a rate of 70. there were no complications from the procedure. the next morning he underwent electrophysiology study and a permanent pacemaker was placed. again there were no complications from the procedure. prior to pacemaker placement, lopressor was held. however, after pacemaker placement, lopressor was reinstated. pump. echo will be checked on the patient prior to discharge especially with the patient's history of chronic lower extremity edema. various differential diagnosis for new complete heart block includes infection such as lyme or syphilis, serology pending; ischemic cardiomyopathy; valvular disease; endocarditis. disposition: the patient will be discharged home. he received p.t. and o.t. prior to discharge. discharge medications: unchanged. , m.d. dictated by: medquist36 procedure: initial insertion of dual-chamber device initial insertion of transvenous leads [electrodes] into atrium and ventricle diagnoses: esophageal reflux pure hypercholesterolemia unspecified essential hypertension atrioventricular block, complete hip joint replacement 

Answer: The patient is high likely exposed to
