Central blood flow (CBF) was estimated by an intravenous 133-xenon technique in six preterm infants before and after administration of indomethacin for closure of patent ductus arteriosus. CBF fell in all infants (range 12%-40%), the mean fall was 24% (P less than 0.005). Though none of the infants

## Abstract Extrasystoles occur in normal subjects but are significant more frequently (16.25% vs. 55%; χ^2^ = 19.3; __P__ < 0.001) seen in Parkinson's disease (PD) patients. The extrasystolic decreases in stroke volume and systolic pressure activate sympathetic vasomotor innervation and lead to a
