thrill

a vibration caused by the movement of fluid felt by the examiner on palpation. Created by turbulence in a fluid column passing through an incompetent valve, or from a vessel of smaller caliber to a larger. The larger the orifice the bigger the thrill. Also by sharp firm percussion on one part of the abdomen and feeling a shock wave over a distant part of the abdomen—the so-called fluid wave.
