Objective Detecting paroxysmal atrial fibrillation in patients with ischemic stroke presenting in sinus rhythm is difficult because such episodes are often short, and they are also frequently asymptomatic. It is possible that the ventricular repolarization dynamics may reflect atrial vulnerability and cardioembolic stroke. Hence, we compared the QT-RR… (More)
The aim of this work is to give a twistor presentation of recent results about bi-Hermitian metrics on compact complex surfaces with odd first Betti number.
Sleep of 6 depressed patients with hypersomnia was studied during their depressed phase and their remitted phase using 24-h polygraphic recording. Nine normal subjects were studied as the controls. The latency to sleep onset of the depressed patients was significantly shorter than that of the remitted patients and that of the control subjects. The total… (More)
