Precordial Catch syndrome is a condition characterized by extreme chest pain, painful breathing, and a "popping sensation" while taking deep breaths. Precordial Catch is a common cause of irregular chest pain, often mimicking signs of (what one would guess is) a heart attack. Precordial Catch syndrome was first described by Drs. Miller and Texador in the 50s, and was subsequently named by the duo.
The condition is not believed to be dangerous. Precordial Catch is still much of a mystery to doctors, and there is no known cure. That being said, the syndrome is not thought of as harmful by most health professionals.
Precordial Catch is very commonly in young adults. Children, teenagers, and young adults have most of the reported cases of Precordial Catch. Adults do also get the condition from time to time as well, albeit at a lower rate.
Symptoms usually start with a chest pain. What characterizes Precordial Catch syndrome is a sudden wave of pain on the left anterior side of the chest. Said pain is increased with breathing, although it always will be localized (unlike a heart attack).
Popping sensations. Deep inhalations have been reported to increase the pain people experience. Some have found the waves of pain to be ended by taking deep breaths, waiting for a "popping" or "ripping" sensation, and then exhaling.
Episodes usually don't last long. Most Precordial Catch experiences last a few breaths, seconds, or minutes. It is possible that Precordial Catch episodes can occur several times a day, although infrequently.
PCS (as the syndrome is often abbreviated to) is still much of a mystery. Its origins are unknown, although Miller and Texidor ruled out the heart. Treatment varies, but the worst symptom (for many) is often the looming fear of a heart attack, which is not the case. Please consult your physician immediately if you have consistent heart pain (at all).
