Cardiodoron consists of an extract of Primula off. flos 2,5 g, Onopordon acanth. flos 2,5 g and Hyoscyamus niger herba D 2 10,0 g/100 g. According to general experience (Weckenmann 1981) and systematic testing it is indicated in the case of vasolability and orthostatic hypotension. Figures 1-3 illustrate this by means of pulse, pulse-respiration quotient (Q P/R) and orthostasis quotient. For a better understanding of these parameters we will explain them for orthostatic lability: in terms of pulse reaction a tachycardic and a bradycardic form can be recognized. …
