What is another word for cardiospasm?
Pronunciation: [kˈɑːdɪˌə͡ʊspazəm] (IPA) 
Cardiospasm is a medical condition that affects the lower esophageal sphincter, which hampers the process of food and liquid transfer between the esophagus and the stomach. The symptoms include chest pain, difficulty swallowing, and heartburn. However, there exist several synonyms for the term cardiospasm such as achalasia, esophageal achalasia, and cardiospasmus. Achalasia derives from a Greek word meaning "failure to relax," referring to the esophageal muscles in this context. Esophageal achalasia is another term, denoting the difficulty in food passage to the stomach due to the unrelaxing esophageal muscles. Cardiospasmus is yet another synonym that represents difficulty in the relaxation of the lower esophageal muscles.
