I have been having spells that last about 30 minutes to an hour where i feel very lightheaded and disconnected, uncoordinated, and need to lay down. Things that help it sometimes if at all are laying down or eating. It's not my blood sugar though it was normal during a spell. Sometimes my chest feel heavy or squeeze a little in the center, or like my heart may give out, but I do not have severe chest pain. I'm a 30 year old man. with a normal echocardiogram chest xray labs. I was thinking about maybe an ECG gated CT angio of the heart. Am I a very good candidate to jump right into that test ..? if not, what else should i get done?
