Your description of your symptoms may be all a doctor requires to diagnose heartburn, but sometimes additional testing may be necessary. The esophagus can be viewed through an endoscope, a long, thin, flexible tube inserted through the mouth, or by X-ray.
Sometimes, your doctor may recommend a 24-hour esophageal pH probe study, especially if you have unusual symptoms, such as throat or chest or abdominal pain, coughing, or asthma-like symptoms. In this test, a long, narrow, flexible tube is inserted through the nose down into the esophagus and a probe is left there for 24 hours. This probe detects acid levels to determine if it correlates with your symptoms. A newer technique (called Bravo) measures 24-hour acid; it is done using wireless pH sensors, which eliminates the need for a tube insertion. To detect if your heart is the cause of your symptoms, an electrocardiogram (ECG), a recording of the heart's electrical activity, may be taken.
Despite its name, heartburn has nothing to do with the heart. Some of the symptoms, however, are similar to those of a heart attack or heart disease.
Heartburn is an irritation of the esophagus that is caused by stomach acid. This can create a burning discomfort in the upper abdomen or below the breast bone.
With gravity's help, a muscular valve called the lower esophageal sphincter, or LES, keeps stomach acid in the stomach. The LES is located where the esophagus meets the stomach -- below the...
