Syncope associated with supraventricular tachycardia: Diagnostic role of implantable loop recorders
Annals of Noninvasive Electrocardiology, 2021 Syncope represents a relatively uncommon symptom of supraventricular tachycardia (SVT). It is likely that an impaired autonomic vasomotor response to the hemodynamic stress of tachycardia is the determinant of hemodynamic changes leading to cerebral ...

Folding a 2-D powder diffraction image into a 1-D scan: a new procedure
, 2006 A new procedure aiming at folding a powder diffraction 2-D into a 1-D scan is presented. The technique consists of three steps: tracking the beam centre by means of a Simulated Annealing (SA) of the diffraction rings along the same axis, detector tilt ...
