How is the pulse generated? The pulse is produced as follows: The heart, after having drawn in the air from the lung, first receives it in its left cavity, then falling back upon itself immediately distributes it to the arteries; it follows, then, that, during the collapse of the heart, the arteries of the body being filled, their pulse is produced, and when empty, their systole. As I say, the pulse is produced in the arteries when full and receiving the air, and in the heart when empty, as we establish below. In his view of the contraction of the ventricle being the cause of the dilation of the artery, Harvey was anticipated also in modern times by Csesalpinus, who observes in his Qusestiouum Peripateticarum, 1593, Lib. Quint, Qusest. iiii, p. 122, that it happens that when the heart is contracting, the arteries are dilated, and it dilating, are contracted.''' Cum enim vasorum in cor definentium quoedam intromittant contentam in ipsis substantiam, ut vena cava in dextro ventriculo & Arteria venalis in sinistro qusedam educant, ut arteria aorta iu sinistro ventriculo et vena arterialis pulmonem nutriens in dextro, omnibus autem membranulse sint appositte ei officio delegata3 ut oscula intromittentia nou educant & educentia non intromittant.
