This symptom of heartburn and precordial discomfort after getting up in the morning may be considered to be due to insomnia and dreaminess at night, which occurs after waking up in the morning. It is usually seen in people with disorders of phytonadic dysfunction, or those with cardiac neurosis. Patients are advised to have an ambulatory electrocardiogram if necessary to help assess the patient’s overall 24-hour average heart rate and to document whether the patient is experiencing arrhythmias during episodes of discomfort. In some patients, it is not excluded that the symptoms are caused by duodenal ulcer. Some patients present with stomach pain, while others have a predominantly cardiac presentation, especially in elderly patients, where stomach pain and cardiac discomfort are often easily confused. You can also go to the hospital for further examination to clarify the presence of organic lesions.
