The Braun valves enable the combination of two linear vertical conductors and so the tracing of the horizontal projection of the electrical heart Vektor. The figures so obtained were called Planogramme (PG) by us. (Synonyms: vektodiagram, monocardiogram, triogram, etc.) Owing to difference in form and conductibility of the tissue, the heart potentials in the human body are unequally distributed, wherefore, the law of projections, underlying the Einthoven triangle, is not quite perfect. The errors resulting therefrom are particularly apparent in planography. The present paper examines the matter of the distribution of the potentials in the human body for the purpose of drawing conclusions therefrom for the planogrammes and their interpretation. These researches show that one of the most advantageous conductors consists in selecting for the horizontal conductors a plane situated below the heart. The distance, which guarantees agreement of the straight and oblique PG, stipulates that this plane should be situated in the region of the cristae iliacae. The the Braun

The presence of coronary thrombosis was definitely observed once in two generations (mother and son, very similar electrocardiograms) and once in one generation, in two brothers in the early fifties. .The one brother of the latter pair had at the same time a of the extremities, which points to the possibility of the Buerger disease of the arteries presence of arteriitis stenosana coronariae (von Albertini) as the cause of the coronary In a further observation, father and son, coronary thrombosis could be assumed thrombosis. with great probability.

Infarc-

Contrary to the opinion of many outstanding authors it is stated that in most cases of coexistence of bundle branch block and myocardial infarct, the electrocardiogram permits an easy recognition of the existence of the latter. The diagnosis of posterior infarcts is made exclusively by the changes observed in the standard leads; in anterior infarcts by these and by changes in the precordial leads-suBicing in general C, and C, not being necessary to take multiple precordial leads. In the standard leads the ftidamental changes are seen in the S-T segment and T wave: their displacement instead of occurring in the same dire&ion which is opposite to that of the greater wave of the QRS complex-as is characteristic of bundle branch block-occurs is elevated the T wave is inverted, and vice versa. in alternative sense : if the S-T segment 53;:
