Abnormal respiration and sudden death during sleep in multiple system atrophy with autonomic failure.

Abstract

We studied respiration during sleep in 7 patients with multiple system atrophy and autonomic failure (MSA-AF) and 7 control subjects. Although mean respiratory rate, tidal volume, and inspiratory flow rate were statistically similar in both groups, the coefficients of variability in all were significantly greater in MSA-AF patients. Four of 5… (More)
