Liver pulse

Liver pulsation is an auxiliary examination method used to check whether the liver pulsation of the abdominal liver is normal. Liver pulsations include conductive pulsations and dilated pulsations. Conductive pulsation is caused by the liver transmitting the pulsation of the abdominal aorta below it. Dilated pulsation is caused by the contraction of the right ventricle to the liver through the right atrium and inferior vena cava. The examination method to distinguish the two is to place the patient in an upright position, with the examiner pressing one hand on the front of the liver and the other hand on the back of the liver. If both hands feel that the liver is in sync with the heartbeat (equivalent to the late systole), then it is a dilatational beating of the liver; if only the hand in front of the liver has this feeling, the hand behind the liver does not have this feeling, indicating that the liver is conducting pulse .
