数脉息间常六至，阴微阳盛必狂烦。
—— 濒湖脉学 · 数脉 · 体状诗
The rapid pulse delivers six beats to a breath: when yin is faint and yang flourishes, agitation and restlessness must ensue.
一息五至以上（每分钟九十次以上），脉来急促。
Five or more beats per breath (over ninety per minute); the pulse comes in urgent succession.
主热证。数而有力为实热；数而无力为虚热，多见阴虚内热。亦见于气血虚、阳气外浮之危候。
Chiefly indicates heat. Rapid with force denotes excess heat; rapid without force denotes deficiency heat—most commonly yin deficiency with internal heat. In severe qi-blood deficiency or yang desertion outward, a rapid forceless pulse is a critical sign.
