Roemheld syndrome (RS), or gastrocardiac syndrome, or gastric cardiac syndrome or Roemheld-Techlenburg-Ceconi-Syndrome or gastric-cardia, was a medical syndrome first coined by Ludwig von Roemheld (1871–1938) describing a cluster of cardiovascular symptoms stimulated by gastrointestinal changes. Although it is currently considered an obsolete medical diagnosis, recent studies have described similar clinical presentations and highlighted potential underlying mechanisms.
