Abstract
Hemodynamics in the esophageal mucosa of 70 patients with abnormal sensation in the esophagus was examined by reflex-photoelectric plethysmograph using cadmium sulfide (Cd S) cell as transducer.
Patterns of volume pulse wave obtained were divided into 5 groups according to variation of base line, property and form of wave. In the esophageal mucosa, dicrotic wave was most frequently observed. There was a certain relationship between volume pulse wave and aging. The pulse waves in patients with esophagitis, cancer of the esophagus and achalasia were also recorded and abnormal change of hemodynamics was suspected. As a result of these, the esophageal mucosa was stongly effected by heart rate and respiration and was very sensitive to aging and diseases.
