Abstract
An apparatus for automatically detecting a posterior ischemia includes a multi-element esophageal electrode coupled to an artifact suppressing circuit and a cardiac stimulator. Output from the artifact suppressing circuit, the detected QRS wave, is processed in analog and digital filters. The processed signal is analyzed to automatically determine the presence or absence of the posterior ischemia.
