How often is chest pain caused by hyperventilation?
One study suggests that up to 90% of non-cardiac chest pain is thought to be induced by hyperventilation (De Guire et al 1992) Syndrome X refers to patients (mainly women) who get a history of angina with positive exercise test, but normal angiography. This is thought to be due to a functional abnormality of coronary circulation. Can hyperventilation cause a heart attack? In very rare cases, people who hyperventilate can have lower carbon dioxide blood levels that can cause a spasm of the blood vessels that supply the heart. If you already have heart disease, this spasm may be enough to cause a heart attack. The majority of patients with hyperventilation, the chest pain is due to UDB and attempted over-inflation of the lungs. Without thinking about it, you might use your chest muscles to try to expand your rib cage. This extra muscle work will feel like shortness of breath, and you’ll have difficulty in taking a deep breath. Your chest muscles will become tired, just like your legs tir
