Multichannel intraluminal impedance (MII) is a relatively new technique that enables detection of retrograde and antegrade bolus movement along the esophagus. This chapter reviews the basic principles of intraesophageal impedance measurement and its application to esophageal function testing (EFT) and gastroesophageal reflux (GER) monitoring. The clinical and research applications of impedance combined with manometry for EFT and impedance combined with pH‐metry for GER monitoring are discussed in greater detail in Chapter 11.
