<s>[INST] Hi. First of all sorry if my english is not so good, for i am portuguese. My problem is this i have bradycardia and i am not fit, it was detected in an ekg, however my doctor says everything is fine with me. Sometimes i feel dizzy, my head hurts in one side, i nauseated and i get pale. And i also have anxiety, in matter of fact, sometimes i get the feeling i am about to lose consciousness or about to die. Please help me. I have done a lot of tests but my doctor always say i am fine. [/INST] Hi, For some people bradycardia is normal, as their heart rate is always slow, and their organism used to work under that heart rate. If you have bradycardia always it means it is your normal heart rate. If your heart rate slows down only when you feel dizzy, then your symptoms are associated with bradycardia. You should check your heart rate when you feel well and during your symptoms. If the difference is not much, most probably your symptoms are related to anxiety or panic attacks. If the difference is big, then your symptoms are caused by bradycardia. Hope I could help nourishing you good health In case of further questions don't hesitate to ask </s>
