Decreased heart rate variability predicts death in amyotrophic lateral sclerosis.

Abstract

INTRODUCTION Some patients with amyotrophic lateral sclerosis (ALS) die suddenly despite normal nocturnal pulse oximetry (NPO), possibly due to dysautonomia. METHODS Forty-four ALS patients without other medical conditions were studied. Heart rate variability was assessed through finger oximetry. The heart rate coefficient of variation (HR CV) was… (More)
