Not illustrated. 1914 edition. Excerpt: ...in blood-pressure. IX.--Lumbar Puncture. Conclus1ons. (1) We do not feel that either of the methods studied offer any especial advantages over the routine blood-pressure observation. The calculation of the energy index perhaps helps us to visualize more clearlv just how much energy the heart is expending, but the "cardiac load " feature teaches us nothing that is not evident from the mere inspection of the diastolic and the pulse pressures. (2) When the results obtained by the two methods coincidently in a given case are contrasted they are often found to vary not only quantitatively, but often qualitatively. Either method is more useful for the continuous study of a given case than it is for the purpose of comparing different cases or for gathering statistical data. (3) Comparative daily observations of the " cardiac load" and the " energy index " throw some light upon the progress of ti1e circulatory function, but identical figures may be obtained from a dying heart and from an organ which still has a good functional capacity and a large reserve force. (4) The diastolic pressure which is now readily obtained by the auscultatory method is often of greater importance than the svstolic pressure, which varies much more widely as the result of psychic processes and other evanescent causes. The discussion on this paper will be found combined with that on Dr. Rochester.s paper on p. 300. HOW SHALT. WE TELL WHETHER THE MYOCARDIUM IS COMPETENT? By JOHN M SWAN, M.D. ROCHESTER, NEW YORK. The determination of the functional capacity of the vital organs is a problem that is of the utmost interest in prognosis. If a man consults a physician for symptoms pointing to disturbance of the heart, the kidneys or the liver, it...show more
