BACKGROUND Data on relative safety, efficacy, and role of different percutaneous left ventricular assist devices for hemodynamic support during the ventricular tachycardia (VT) ablation procedure are limited. METHODS AND RESULTS We performed a multicenter, observational study from a prospective registry including all consecutive patients (N=66) undergoing VT ablation with a percutaneous left ...

BACKGROUND In ventricular scar, impulse spread is slow because it traverses split and zigzag channels of surviving muscle. We aimed to evaluate scar electrograms to determine their local delay (activation time) and inequality in voltage splitting (entropy), and their relationship to channels. We reasoned that unlike innocuous channels, which are often short with multiple side branches, ventricu...

The aim of the study was to assess the instantaneous spectral components of heart rate variability (HRV) and systolic blood pressure variability (SBPV) and determine the low-frequency (LF) and high-frequency baroreflex sensitivity (HF-BRS) during a graded maximal exercise test. The first hypothesis was that the hyperpnea elicited by heavy exercise could entail a significant increase in HF-SBPV ...

Objective: Determine the validity of the TRT_S2012 software in to assess the total reaction time (TRT) with a simple visual stimulus (TRTSimple) and mental fatigue from TRT (TRTFatigue). Methods: Three types of validation were applied: a) concurrent, for determining the correlation between the TRT_S2012 Software and Vienna Test System (VTS), b) content of a sample of adults, and c)mechanical, u...

Purpose The COVID-19 pandemic has forced many organisations to transform face-to-face teams into virtual ones through the adoption of remote working modes. This event represented starting point a process that is changing how management control (MC) systems are designed and implemented guide employees towards organisational objectives. previous literature on (VTs) devoted scant attention MC issu...

Patient motion is inevitable in SPECT and PET due to the lengthy period of time patients are imaged. The authors hypothesized that the use of external-tracking devices which provide additional information on patient motion independent of SPECT data could be employed to provide a more robust correction than obtainable from data-driven methods. Therefore, the authors investigated the Vicon MX vis...

Vector Taylor Series (VTS) is a powerful technique for robust ASR but, in its standard form, it can only be applied to log-filter bank and MFCC features. In earlier work, we presented a generalised VTS (gVTS) that extends the applicability of VTS to front-ends which employ a power transformation non-linearity. gVTS was shown to provide performance improvements in both clean and additive noise c...

Image sizes have increased exponentially in recent years. The resulting highresolution images are typically encoded in a lossy fashion to achieve high compression ratios. Lossy compression can be categorized into visually lossless and visually lossy compression depending on the visibility of compression artifacts. This dissertation proposes visually lossless coding methods as well as a visually...
