The present study investigated the inhibitory effect of visual distractors on the latency of saccades made by hemianopic and normal human subjects. The latency of saccades made by hemianopic subjects to stimuli in their intact visual field was not affected by visual distractors presented within their hemianopic field. In contrast, the latency of saccades(More)
Twenty-three patients underwent implantation of a stimulator system and were followed for 6-20 months. Twenty patients estimated between 50% and 100% pain relief. The effect was largely consistent and reproducible. Reduced drug intake and improved social performance were associated with subjective improvement. The surgical technique is given, complications(More)
AIMS Large randomized trials comparing DDD with VVI pacing have shown no differences in mortality, but conflicting evidence exists in regard to heart failure endpoints. Here we evaluated the effect of pacing mode on serum levels of brain natriuretic peptide (BNP) and amino-terminal-proBNP (NT-proBNP). Methods Forty-one patients (age 73 +/- 10 years) with(More)
BACKGROUND AND OBJECTIVE Far-field R wave sensing (FFS) in the atrial channel of dual chamber pacemakers is a relevant source for inappropriate mode switch from the DDD mode to the DDI or VDI mode. Inappropriate loss of atrioventricular synchrony due to false positive mode switch is hemodynamically disadvantageous, may induce atrial tachyarrhythmias, can(More)
From 1980 to 1992 we followed 12 patients with cardiac myxomas for an average of 4.4 years (8 months-11 years). Presenting symptoms were neurological in four patients (hemiparesis, aphasia, visual field deficits, progressive dementia or vertigo), progressive dyspnoea in six, pulmonary embolism in one, and peripheral arterial or renal emboli in three. The(More)
BACKGROUND Percutaneous coronary intervention (PCI) is the most effective reperfusion modality in patients with acute myocardial infarction (MI). Data concerning long-term survival and functional outcome are sparse. METHODS One thousand consecutive patients treated by emergency PCI were systematically ana-lysed in a single-centre registry. Multivariate(More)
An analysis of the essentials of both external and implantable neurologic stimulation devices is presented. Specific system requirements have been extracted from clinical experience with neurologic hardware for pain inhibition. Application of these devices includes dorsal column stimulation, transcutaneous nerve stimulation and peripheral nerve stimulation.(More)
