A fast pulse means that the pulse rate is greater than four to one breath. Weak pulse is a modern word, a proper noun, referring to a pulse that comes in thin and soft and sinks, tender and slippery. Weak pulse is mostly seen in the deficiency of qi and blood. When the blood is deficient and the pulse path is not full, the pulse is thin; when the qi is deficient, the pulse is weak, and the pulse is dull, soft and feeble. If the pulse is weak or even disappears during inhalation, it is called Qi Pulse. Odd pulse is one of the important signs of pericardial tamponade, mainly due to the decrease of left ventricular output. In pericardial tamponade, the increase in negative chest pressure during inspiration increases the volume of blood in the pulmonary circulation, but because of the restriction of cardiac diastole, the return flow from the circulation to the right ventricle cannot be increased accordingly.
