Relationship between distension-contraction waveforms during esophageal peristalsis: effect of bolus volume, viscosity, and posture
{{output}}
High-resolution esophageal manometry (HRM) in its current form assesses only the contraction phase of peristalsis. Degree of esophageal distension ahead of contraction is a surrogate of relaxation and can be measured from intraluminal esophageal impedance meas... ...
