The development of left ventricular torsion and its clinical relevance

“…In the famous publication by Sir William Harvey in 1628, 'Exercitatio Anatomica De Motu Cordis et Sanguinis in Animalibus', a twisting motion of the ventricle during contraction was first described after observation of open chested animal hearts [1]. However, it was Streeter and colleagues in the late 1960s following a study of pathological canine specimens who further qualified the phenomenon in detail [2].…”

The Nature of Science

“…It is interesting to compare two initiated in the seventeenth century, the concepts of force and of virus (Harre 1972 but not essential; the energy exchanges can be adequately explained without it. On the other hand the axiom of virus is essential to the understanding of a large group of diseases.…”

“…' In this brief study of the nature of science from a philosophic point of view, I shall first propose some definitions, then study the patterns of scientific procedure and some relevant metaphysical principles, then consider what constitutes science, and finally say a few words about its purpose. DEFINITIONS Science has been defined as 'the state of knowing' (Onions 1947), as 'the systematic pursuit of knowledge' (Russell 193 l), as 'an intellectual exercise aimed at understanding the world' (Harre 1972), and as 'that branch of pure…”

Coupling analysis of transient cardiovascular dynamics

“…Another measurement is the beat-to-beat blood pressure recording, whose most important development stations encompass among others the hydraulic function of the cardiovascular system [Har28], the realisation that respiration causes blood pressure fluctuations [Hal33,Lud45], and the discovery of rhythmic blood pressure fluctuations, the so-called Mayer waves [May76]. Blood pressure is usually described by the two variables of systolic and diastolic blood pressure, i.e.…”
