FOr the Symptomes of the vital faculty there is a palpitation of the heart (a Lypothymy, * 1.1 or an absence of Spirits for a short time) or an Aphyxy, or no Pulse. Palpitation of the heart is when there is a depraved motion of it, swifter then it ought to be, when the heart leaps and strives to fly from that which troubles it.
A Lypothymy, * 1.2 or want of vital spirits is when the Pulse beats swift on a sudden, and then ceaseth to beat at all, or is suddenly taken away with a small, slow and weak Pulse, to which some add an Eclusie, or absense of the vital soule.
A Syncope again is a motion depraved, * 1.3 when the Pulse is much lesser, slower, and weaker then a Lypothymy.
An Asphuxy is a total absence, as it were, of the Pulse, and the highest degree of swooning, and neerest to death: of the other preternatural differences of Pulses we will speak in another place.
Respiration, which is caused by the heart, * 1.4 either is wholly ta∣ken away, Which Symptome the Greeks call Apnoia, or is de∣praved, which they call Dyspnoia; besides these, the respiration is either too great, or too small; too often, or too seldome; too swift, or too slow; equal, or unequal. And lasty, of swift and slow breathings, there are some differences, according to more and lesse; for the first degree is a Dusopme, the second is an Asthma, the third is an Orthopnie, when the sick are forced to fit upright to breath.
