I had an aicd implanted back in August 2011. I am service connected for hypertension,diabetes,neuropathy,hiatal hernia,hypertensive vascular disease. I went and applied for compensation for the aicd and did everything and got denial letter. I talked to dav and they told me that if I had an etiology for service connected they would approve it. So I went and got copy's from the va and the reason for aicd was arrythmia,and provisional diagnosis is paroxysmal super ventricular tachycardia. I am asking for help. If you see the causes for arrythmia some of them are high blood pressure,diabetes and etc. so I am seeing with help of people do you think I should appeal my denial letter since I found out reason for implant was arrythmia or don't because I don't have good reasons. If you can help me please . Tom
