I've found ER's are mostly a placebo service making one think they are in the safest place possible. I can't say with your limited details but as shocking as it sounds, schizophrenia has been linked to allergies to some foods when the chemicals pass the blood/ brain barrier. Your heart issue may be related to a syndrome called POTS but again, I don't have enough details to know. You are going to beat yourself to death trying to find your answers with normal doctors. Most only push a pill and its all guesswork. If you want real answers, you need to go to a functional integrative doctor who seeks to find the root cause of an ailment. This takes time and to make it easy on you, most of people's ailments are food-related. What we eat isn't the same as what our parents ate. New chemicals, pesticides, emulsifiers, food additives, etc are in our foods. Processing changes the shape of food chemicals that were once healthy into being tolerable by many but toxic to others. If you try to tell that to your doctor, he or she is likely to fire you as a patient. They have a business to grow and with so many people finding cures by eliminating foods, their bottom dollar is hurt as return customers don't need doctors anymore. Check out doctors like Dr. Ken Berry, Dr. Mark Hyman, and Dr Peter Osborne. They will help you with online videos that actually bring results if you will agree to stop believing that healing happens from a pill. It doesn't. What you put in your mouth is code. That code tells the system how to behave just like a computer. Food is Code. We use it like it was meant for pleasure. Its meant to keep us alive. Good Luck
Everyone can switch their breathing to manual mode, hence the reasons yoga and other meditation activities focus on it. In some people they can begin to panic and wonder if they are breathing at a fast enough rate. As soon as you are distracted and your mind turns to something else, breathing returns to automated mode. When you get into the manual breathing situation, don't worry because if you don't breathe for a while, your brain will override and force you to breathe. It's not possible to hold your breathe and suffocate yourself to death. If you by chance pass out, breathing will return instantly to normal. To ensure this doesn't happen, just totally relax and take a normal breath every 5 seconds. This is adequate and then try to put your thoughts onto something else.
Well I don't know that the doctors were not trying, you ripped off the test instruments..not them. It if troubling, however, that when removed the test leads and an alarm went off there was not response, not even a nurse?
I find If I think "too" much about breathing I find I have to force myself to breath... this goes on for a while and somehow (don't know what) I start breathing normally/automatically again. I do not have any episodes, however, of stopping breathing until it makes me dizzy, and not know it.
My breathing problems is in these cases is more mental, I think.
I also suffer from obstructive sleep apnea, a very mild case, but I don't think this relates to your symptoms.
Do you detect any heart rhythm problems? I suppose if you did it still wouldn't be the source of your breathing problem.
