Although astronauts’ cardiovascular function is normal while they are in space, many have altered haemodynamic responses to standing after they return to Earth, including inordinate tachycardia, orthostatic hypotension, and uncommonly, syncope. Sim

Although humans hold great advantages over other species as subjects for biomedical research, they also bring major disadvantages. One is that among the many rhythmic physiological signals that can be recorded, there is no sure way to know which indi

Because it is likely that, in healthy human subjects, baroreflex mechanisms operate continuously, independent of experimental interventions, we asked the question, In what ways might study of unprovoked, very infrequent muscle sympathetic bursts info

Spaceflight is associated with decreased orthostatic tolerance after landing. Short-duration spaceflight (4–5 days) impairs one neural mechanism: the carotid baroreceptor-cardiac reflex. To understand the effects of longer-duration spaceflight on b

Frequency-domain analyses of R-R intervals are used widely to estimate levels of autonomic neural traffic to the human heart. Because respiration modulates autonomic activity, we determined for nine healthy subjects the influence of breathing frequen

Lidocaine directly affects conduction and refractoriness of ventricular myocardium, and may also indirectly affect these electrophysiologic properties by inhibition of cardiac sympathetic nerve traffic. Both effects may play important roles in preven

Although sympathetic mechanisms play a major role in buffering abrupt arterial pressure reductions, including those that occur during tachyarrhythmias, human sympathetic nervous system responses to ventricular tachycardia have not been measured. Musc

We conducted this study in an effort to characterize and understand vagal abnormalities in heart failure patients whose sympathetic activity is known. We measured sympathetic (peroneal nerve muscle sympathetic recordings and antecubital vein plasma n

We studied the effects of mechanical lung inflation on respiratory frequency R-R interval and arterial pressure fluctuations in nine healthy young adults undergoing elective orthopedic surgery. We conducted this research to define the contribution of
