Usefulness of Monitoring Left Ventricular Function by an Ambulatory Radionuclide Detector (VEST) in Patients with Parkinson’s Disease and Postural Hypotension
Chapter
Abstract
Autonomic dysfunction is a common feature of Parkinson’s disease (PD), and orthostatic hypotension (OH) is perhaps its most disturbing form.1,2 Moreover, the treatment with levodopa, by diminishing the secretion of renin,3 could further exacerbate the occurrence of OH.4 Several techniques have been utilized to study the dysautonomy of PD patients: the most common are the beat-to-beat variation,5 the controlled-hypertermia heat tolerance test,6 the application of lower body negative pressure7 and the power spectral analysis of heart rate and blood pressure.8
