Human Respiratory-Cardiovascular Interactions in Health and Disease
During quiet breathing, healthy humans have strong respiration-related waxing and waning of cardiac-vagal and muscle sympathetic nerve activities (Eckberg et al. 1985). This chapter reviews respiratory modulation of human autonomic cardiovascular outflow and the distortion of this physiologic mechanism that occurs in heart failure patients.
