Hi, My husband is 35 and has recently started haveing health problems. He has rapid heart beat, a gland in his left armpit that swells off and on, muscle spasms in the chest and his primary doc said his liver enzyme is slightly elevated. He has seen a cardiologist which told him that he has artierial flutter/fibralation. They sent him to a sleep study for sleep apnea and told him that he had such a mild case of sleep apnea that it was his choice weather he wanted the cpap. This has all happened in the past three months. The cardiologist has put him on heart meds which worked for a short period of time but doesnt seem to be helping. He says that his heart does this off and on through out the day. The gland in his armpit if pushed on radiates pain through his left arm, down his back and across his chest. He has had an X-ray and no lumps were found but the his primary doc did feel something small a month ago and agian yesterday but he said that it hasnt increased in size so he does not think its cancer. His primary doc is doing an ultrasound on his stomach next week due to the elevated liver. My question is do you think this could still be arterial flutter/fibralation or could all these symptoms be linked to something else? Any advice would be greatly appreciated.Thank you for your timeTheresa king

Hi Mam Thank for choosing Chat Doctor, you have described three problems altogether which are co-related with each others, Arterial fibrillation/flutter required echo study, and for liver the MRI study would be the best choice instead of sonography, the lymph also needs biopsy study, you have not told anything about your husbands habits, we always ask for complete medical history, for provisional diagnosis and better advise, take good care of your husband, and be in touch with Chat Doctor.
