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: the patient is an 88 year old male with coronary artery disease, congestive heart failure, ejection fraction of 35%, history of ventricular tachycardia, status post icd implantation about two months ago, who has been complaining of frequent icd firing. he comes in today because the device had fired three times the morning prior to admission and five times the morning of admission. he had complained of no chest pain or shortness of breath. he does have some occasional light-headedness but none the last two days. he initially presented with tolerated vt in . he had an unsuccessful attempt at vt ablation in , and had an icd placed on . he has also been on amiodarone, however, at the beginning of , the amiodarone was discontinued by his outpatient cardiologist due to recurrent vt which failed atp. he was then switched to mexiletine with plans for possible initiation of dofetilide three months down the road. during , he had two episodes of single firing of the icd to terminate the ventricular tachycardia. however, as earlier said, the last two days, he experienced eight episodes of firing. icd was interrogated out of the hospital and showed appropriate firing. currently, the patient is completely asymptomatic with no headache, visual changes, light-headedness, shortness of breath, chest pain, abdominal pain, nausea, vomiting or diarrhea. past medical history: 1. coronary artery disease, latest catheterization showing no left main disease, 50% left anterior descending, 70% right coronary artery, and his left circumflex has been recently stented. 2. congestive heart failure. echocardiogram in , reveals ejection fraction of 35%. 3. gastritis diagnosed by esophagogastroduodenoscopy though the patient has been taking proton pump inhibitor only sporadically for this. 4. benign prostatic hypertrophy. 5. recurrent ventricular tachycardia as above. medications on admission: 1. lipitor 10 mg once daily. 2. plavix 75 mg p.o. once daily. 3. magnesium. 4. flomax 0.4 mg. of note, the patient is not taking aspirin on a daily basis and only occasionally is taking protonix. social history: he is widowed and lives independently in a house. he has family in the area. he has about 100 pack year smoking but quit about thirty years ago. no alcohol use for the last ten years or so. family history: no coronary artery disease or arrhythmias. physical examination: temperature is 97.8, heart rate 75, blood pressure 166/68, respiratory rate 14, oxygen saturation 96 to 98% on two liters. head, eyes, ears, nose and throat examination - the oropharynx is clear. the neck showed no jugular venous distention, thyroid within normal limits. lungs showed good air movement, clear to auscultation bilaterally. cardiovascular - s1 and s2 with no murmurs, rubs or gallops. abdomen is soft, nontender, nondistended, normoactive bowel sounds. extremities reveal no edema. of note, the patient has amputation of the right arm secondary to a gunshot wound. laboratory data: his laboratories are within normal limits. hospital course: the patient was admitted to the ccu for monitoring. there was no ventricular tachycardia during his stay here. he was started on low dose beta blocker. on the following day, he was taken to the electrophysiology laboratory where noninvasive programmed stimulation was performed. the clinical ventricular tachycardia was induced several times, and terminated by antitachycardia pacing reproducibly by the icd after reprogramming to a ramp atp protocol was performed. the patient remained stable following the procedure and is being discharged to home. condition on discharge: same as prior to admission, ambulatory and able to perform activities of daily living. discharge status: to home. discharge diagnoses: 1. coronary artery disease. 2. congestive heart failure. 3. ventricular tachycardia, status post icd. 4. gastritis. 5. benign prostatic hypertrophy. medications on discharge: 1. aspirin 81 mg p.o. once daily. 2. toprol xl 25 mg p.o. once daily. 3. lipitor 10 mg p.o. once daily. 4. flomax 0.4 mg p.o. once daily. 5. plavix 75 mg p.o. once daily. of note, the patient does not need to be on antiarrhtyhmic medicaiton for now. if he has frequent vt or recurrent shocks dofetilide can be considered in the future once he has been off amiodarone longer. he will follow- up with his primary cardiologist regarding initiation of ace inhibitor in the future as well as the recent finding of a tsh of 10.0 which will probably need to be rechecked in the context of amiodarone having been discontinued. finally he should follow up with the clinic at in 1 month. , m.d. dictated by: medquist36 d: 12:04 t: 19:21 job#: procedure: catheter based invasive electrophysiologic testing diagnoses: coronary atherosclerosis of native coronary artery congestive heart failure, unspecified hypertrophy (benign) of prostate without urinary obstruction and other lower urinary tract symptom (luts) paroxysmal ventricular tachycardia automatic implantable cardiac defibrillator in situ unspecified gastritis and gastroduodenitis, without mention of hemorrhage 

Answer: The patient is high likely exposed to
