What causes tightness in the chest with a racing heart?
Patient: Looking for causes of several symptoms- been to ER 2x and done many tests with conclusions: my symptoms are racing heart mostly at night during sleep- wakes me up. Then tightness and pressure on chest like bricks on my chest- worse when laying flat. Light headed ness and dizzy spells.....also have more muscle and joint pain than normal and now a sudden weight gain. I am scheduled to do a stress test and sleep test....have worn heart monitor for 30 days and found racing heart occasionally but no diagnosis or treatment yet and has been going on for a year now....interfering with my daily life- fatigued and sometimes have to leave work because chest pressure and feeling of lack of oxygen Doctor: I feel you are having obstructive sleep apnoea which explains most of your symptoms except chest pain.please get sleep test done and if OSA is established  then going for CPAP will solve most of your problem. Please get stress  test done to rule out cardiac cause of your chest pain.
