What does the Edrophonium (Tensilon) test help confirm in patients?

The Edrophonium (Tensilon) test is particularly useful for evaluating neuromuscular transmission and can help differentiate between various conditions. In the context of non-cardiac chest pain, the test is often utilized to assess whether esophageal motility disorders, such as esophageal spasm or achalasia, are contributing to the patient's symptoms.

The administration of Edrophonium, a short-acting acetylcholinesterase inhibitor, can temporarily enhance muscle contraction. In patients with certain esophageal motility disorders, this may lead to a reduction in symptoms or an improvement in swallowing function, which can confirm that the pain experienced is indeed of esophageal origin rather than cardiac. This distinction is crucial for guiding appropriate treatment strategies and alleviating patient anxiety related to cardiac concerns. Hence, the Edrophonium test's role in confirming the esophageal origin of non-cardiac chest pain is well-established in clinical practice.
