cord-006226-fn7zlutj	nan	Abstracts of the 4th annual meeting of the German Society of Clinical Pharmacology and Therapy: Hannover, 14–17 September 1994	1994		.txt	text/plain	25050	1344	50	The following were analysed: heart rate (HR, bpm), pre-ejection time (PEP, ms), ejection time (VET, ms), HR-corrected electromechanical systole (QS2c, ms), impedance-cardiographic estimates of stroke volume (SV, ml), cardiac output (CO, I/min) and peripheral resistance (TPR, dyn.s.cm -5) calculated from CO and mean blood pressure (SBP and DBP according to auscultatory Korotkoff-I and -IV sounds This indicates that 1) about half the rise of HR and CO and half the shortening of PEP is 131-respectively 1~2-determined, 2) that predominant 132-adrenergic responses, whilst not affecting VET, take optimal benefit from the inodilatory enhancement of pump performance, 3) that an additional 131-adrenergic stimulation is proportionally less efficient, as VET is dramatically shortened, thus blunting the gain in SV so that the rise in CO relies substantially on the amplified increase of HR and 4), VET is more sensitive than QS2c in expressing additional 131-adrenoceptor agonism and 5) prime systolic time intervals provide a less speculative and physiologically more meaningful represenation of cardiac pump dynamics than HR-corrected ones.	./cache/cord-006226-fn7zlutj.txt	./txt/cord-006226-fn7zlutj.txt
