OBJECTIVE This study describes changes in heart rate (HR) and HR variability (HRV) related to clinical onset of seizures in nocturnal frontal lobe epilepsy (NFLE) in order to determine whether signs of autonomic activation precede onset of seizure motor manifestations, which was selected as seizure onset (SO). Further, to clarify the nature (epileptic or(More)
Risk factors that can determine knee and ankle injuries have been investigated and causes are probably multifactorial. A possible explanation could be related by the temporary inhibition of muscular control following an alteration of proprioceptive regulation due to the ankle imbalance pathology. The purpose of our study was to validate a new experimental(More)
In recent years, the Autonomic Nervous System (ANS) Evaluation Unit of the University of Bologna and the medical physicists of the School of Medicine have worked together on a project to devise a new integrated approach to investigate the cardiovascular reflexes and study the ANS. Our work stemmed from an awareness of the needs of European ANS units [1],(More)
The analysis of P-wave template has been widely used to extract indices of Atrial Fibrillation (AF) risk stratification. The aim of this paper was to assess the potential of the analysis of the P-wave variability over time in patients suffering from atrial fibrillation. P-wave features extracted from P-wave template together with novel indices of P-wave(More)
Although different systems are available on the market to record ECG and to send it to an analisys station, there is still demand for a more vesatile, easy to use device that shorten the time the diagnosis is available, avoiding the patient to move to a healthcare center: the purpose of our work was to validate a solution that fullfil this requirement.(More)
The aim of this study was to assess the effect of filtering techniques on the time-domain analysis of the P-wave. Multi-lead ECG recordings obtained from chronic AF patients after successful external cardioversion have been acquired. Several high-pass filtering techniques and three cutoff frequency values were used: Bessel and Butterworth four-pole and(More)
