Indigestion and burping are not always indicative of the occurrence of a heart attack, according to the Doctors Hospital. Actually, severe or chronic indigestion, while sometimes a sign of possible heart attack, is not considered so when accompanied by burping. Belching or burping, together with nausea and heartburn, usually indicates nothing more than indigestion.
Indigestion, nausea, abdominal pain or heartburn are considered to be typical heart attack symptoms, according to Mayo Clinic. Other signs include: an aching or squeezing feeling in the arms or chest that might spread to the back, jaw or neck; chest pain; fatigue; and shortness of breath. Symptoms of heartburn include: a sensation of burning that begins in the upper section of the abdomen and moves upwards to the chest, and possible sourness of the mouth, particularly while lying down. Heartburn and burping usually accompany indigestion, points out the Doctors Hospital. The terms "heartburn" and "acid indigestion" are often used interchangeably, according to HealthTap.
Angina, heartburn and heart attack may feel significantly alike, says Mayo Clinic. An emergency clinic immediately runs tests to eliminate heart attack, as even experienced physicians may not be able to determine the cause of chest pain.
Chest pain that persists, and that cannot definitely be attributed to heartburn, suggests a 911 call, recommends Mayo Clinic. An unexplainable episode of chest pain that lasts several hours and then stops warrants discussion with a physician, as symptoms of an impending heart attack can subside before the actual attack.
