In a prospective study, we evaluated the hypothesis that QT variability is abnormal in multiple system atrophy. Time and frequency domain QT variability was assessed from 24-hour Holter monitoring. Three-channel Holter monitoring was performed in all subjects and was analyzed on a homemade analyzer....
