Muscle sympathetic nerve activity during apneic episodes in patients with obstructive sleep apnea syndrome

Muscle sympathetic nerve activity during apneic episodes in patients with obstructive sleep apnea syndrome

Electroencephalography and Clinical Neurophysiology 93(5): 345-352

Muscle sympathetic nerve activity (MSNA) was recorded from peroneal nerve in 4 OSAS patients during sleep. During apneic episode, MSNA was enhanced, but it did not increase progressively toward the end of the apneic episode. MSNA remained at a stable level in the later part of an apneic episode. A surge of MSNA took place just preceding or just at the end of an apneic episode and it was followed by a transient marked blood pressure elevation.
