I am 43 years old and in relatively good shape. Last spring I went to the doctor to determine whether or not I should be worried about ongoing heart palpitations and fatigue. I wore a Holter monitor which showed multiple PVCs. I then had a stress test which was abnormal, which led to a Cardiac Catheterization. During this procedure, they determined that I had Anomalous Left Coronary Artery from the Pulmonary Artery. I have since had open heart surgery and my left coronary artery was transplanted to the correct location.
While in the hospital, recovering, I had multiple events of ventricular tachycardia. One event was 23 beats long, though I am unsure how fast my heart rate was. I was put on Amioderone, Altenolol, aspirin, and Coumadin; however, my blood pressure and heart rate decreased too much on this regimen, and I am now only on 25 mg of Altenolol, low dose aspirin, and 5mg of Coumadin.
I also had a cardiac MRI which showed that my right coronary artery is 11mm in diameter. It also showed the following: probable myocardial infarction, papillary muscle infarction, minimal mitral regurgitation, borderline reduced left ventricular systolic function, mild biatrial and left ventricular dilation, possible bicuspid aortic valve, and a lesion on the right hepatic lobe (possible hepatic hemangioma).
Over the last 3 months, the palpitations have continued. I have had episodes of shortness of breath/breathlessness/starving for air. These occur at random times, but first happened while I was falling asleep. I have had an episode of my vision blacking out upon standing, though I did not lose consciousness. I have had multiple episodes of the edges of my vision graying out. I have also had an increase of twinges (chest discomfort more than pain, accompanied by a feeling tightness, heaviness, or fullness). And, lastly, I am very fatigued.
My local electrophysiologist has referred me to a doctor 3.5 hours away to determine whether or not I will need a defibrillator. I have read multiple articles about these and cannot determine when they are needed. How do the doctors determine whether to treat tachycardia with medicine, ablation, or ICDs? How can I best educate myself and prepare for this doctor's visit?
