My husband survived prolonged V-tach but is now extremely fatigued. Is his heart not pumping efficiently? 

My husband survived a V-tach episode of 290 Bon. He was in V-tach for 40 minutes. He was jogging on the trail and amazingly walked back to the car, a 1.5 mile walk. He coded 5 minutes after admission to ER; saved his life with amiodarone. He had physiology tests and found that he has an abnormality of the right ventricle, he has fatty tissue replacement, but missing EKG criteria for an ARVD DX. His specialist implanted an ICD because he is considered high risk. His diagnosis is monomorphic ventricular tachycardia. Question: Since his episode and ICD placement, he has nausea (no meds, sotalol made him feel worse) lightheadedness, heart palpitations, very, very tired, struggling to get through work each day. Why does he feel like this? Is it the fact that his heart does not pump efficiently? His EF for RV is 37 and EF for LV is 53. Will he continue to get worse? I understand he has a less chance of dying suddenly with the ICD but something has dramatically changed since this V-tach episode. He does not have any other heart issue, arteries and veins all clear. He did have an older brother that died suddenly at age 50 of a heart virus. Our doctor acts like he doesn't know what to do for him since he survived this! Very maddening. Another clinic told us that it's a "very challenging" heart case. Don't understand why he feels so bad, when they won't tell us anything! Frustrated. Any answer helps. Thanks so much.

Scott R. Sherron, MDI agree that it is unusual for him to have this degree of symptom as a result of a survived sudden death episode without other ongoing cardiac issues. A reduced EF in the RV can lead to swelling and, if increased pressure in the liver, to nausea.  An EF of 53% is at the low end of normal for the LV (50-70%) and therefore unlikely to lead to such profound fatigue, but it may still represent a decrease from his prior function and therefore be contributing. If it has been less than 3-4 months since the event, he may still be in a recovery phase that can be expected to improve. If there is a viral component to his cardiac issues, it only rarely worsens and can actually return to normal function over the course of 6-12 months. The cause of the palpitations should be easy to detect from the ICD.  Depression can be a common feature after any major heart event and sometimes presents with similar symptoms, especially in someone without prior depressive tendencies. I understand that I am listing a lot of "maybes" but it is difficult to assess without more data. Also, if there were easy answers, you would likely have received them already. I hope this offers some fodder for further thought and evaluation and I hope that his symptoms improve.
