Contractile Properties of Esophageal Striated Muscle: Comparison with Cardiac and Skeletal Muscles in Rats

Figure 2

Multipulse electrical stimulation-induced contractile responses of esophageal, skeletal, and cardiac muscles. Representative traces of the contractile responses to single and multipulse repeated EFS in esophageal (a), skeletal (b), and cardiac (c) muscle preparations are shown. Similar results were reproducibly obtained in five independent experiments. EFS was applied by using single or repeated pulses (80 V-10 ms, 20 Hz for 1 s). Closed circles and underbars indicate the points of single EFS and the location of multiple EFS, respectively.
