<s>[INST] my husband is dissy. He has ekocardiogram. which was good. also all sorts of blood test. nothing there. He doesn t sleep well and wakes he wakes up during the night with numb hand or leg. I have had to call 911 at night twice in the last 3 months because he felt dizzy at night and fainted. He is 64 not over weight much. The Dr gave him a blood meter I just tested it and it was 72 he ate a peanut butter sandwich. 30 min later it was 82. He also belches alot. What do you think [/INST] Hello, If he fainted at night and is complaining of dizziness then, at this point I still believe he needs a cardiac workup which should include a 12 lead ELECTROCARDIOGRAM (EKG) along with a HOLDER OR EVENT monitor which will monitor his heart rates and rhythms since he may be suffering from a cardiac arrhythmia causing him to feel this way or pass out.  Another specialist who may be able to help is a neurologist in order to make sure that he is not suffering from severely decreased blood flow to the brain through either the carotid artery system or the posterior vertebrobasilar system which also cause dizziness and fainting if not enough blood is reaching the brain.  Yet another thing that the neurologist may consider would be a SEIZURE DISORDER that can both cause dizziness during an attack and fainting (referred to as the POSTICTAL STATE if it is a seizure event). Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.  </s>
