Synchronous electrogastrographic and manometric study of the stomach as an esophageal substitute

Table 3 The response to a test meal of mechanical activity in the stomach of healthy volunteers and of esophagectomized patients with a transposed stomach, expressed as the number of contractions per minute. The electromechanical fractions express the percentage of the dominant frequency that develops mechanical contractions.
