In anatomy, the precordium or praecordium is the portion of the body over the heart and lower chest.
[1] Defined anatomically, it is the area of the anterior chest wall over the heart.
The precordium is naturally a cardiac area of dullness.
In fact, this area only gives a resonant percussion note in hyperinflation, emphysema or tension pneumothorax.
Precordial chest pain can be an indication of a variety of illnesses, including costochondritis and viral pericarditis.
