2) Nausea, vomiting and burning sensation of the stomach
When a part of the heart is not well perfused with blood, it is termed “ischemic”. Ischemic areas tend to irritate the nerve close to them -also known as the vagus nerve-, and when they do, it induces a sensation of nausea and perhaps even vomiting. A burning sensation of the area just under your chest (the epigastrium) may also be felt as a result of irritation of the diaphragm over which the heart lies. Such symptoms should never be ignored, and heartburn is often considered sufficient to perform an ECG in the ER.
