S. RODBARD AND H. SAIKI (Am. Heart J., November, 1953) have studied the fiow of liquid through collapsible tubes by means of pressure and sound recordings, stroboscopy and high-speed cinematography. They have found that fiow through a partially stenotic collapsible vessel sets up a repetitive opening and closing of the tube. Drops of a specific shape are extruded as a result of this fiittering motion, and sounds with a murmur-like quality are produced. The mechanism of murmur production is seen as due to the repetitive interchange at rapid rates of the energy of the stream from lateral pressure to velocity.
