heart failure
In 28 heart failure patients (NYHA functional class       II) under conventional treatment we measured plasma norepinephrine and efferent       postganglionic muscle sympathetic nerve activity (microneurography) at rest and       during arterial baroreceptor stimulation and deactivation induced by stepwise       intravenous infusions of phenylephrine and nitroprusside, respectively.
