Does rate-adaptive pacing using intracardiac impedance show no evidence for positive feedback during dobutamine stress test?
In patients implanted with the Inos2 DDDR pacemaker acute stimulation with intravenous dobutamine leads to a robust increase in paced heart rate without any evidence of positive feedback.
Despite global similarities in cognitive performances between DLB and PDD patients, we observed important differences: in particular, DMS-48, a test of visual object recognition memory and visual storage capacity, was poorer in DLB patients.
