The new generation of Implantable Cardioverter Defibrillators (ICDs) allows storage of intracardiac electrograms (EGMs) recorded immediately before the onset of malignant ventricular tachyarrhythmias (VTs) and during their course. Although all devices base most of diagnostic parameters on the bipolar EGMs, some of them allow two types of EGM recordings:(More)
Ventricular tachyarrhythmia (VT) onset is studied by reviewing spontaneous intracardiac electrograms (EGMs) from coronary artery disease (CAD) and dilated cardiomyopathies (DCM) patients with implantable cardioverter-defibrillators (ICD). A total of 165 VT episodes (79 CAD and 86 DCM) from 37 patients (26 CAD and 11 DCM) are analysed. Modes of VT onset are(More)
Growth, weight at birth and daily weight gain (DWG) on 12 water buffalo calves, starting from 6 days of age until completion of weaning, was investigated in this study. Different feeding regimens were given to two groups of animals with regard to daily milk replacer: (1) group 1 (G1) received a double concentration in single administration; whereas (2)(More)
Aim: Coronary Artery Disease (CAD) and Dilated Cardiomyopathy (DCM) are structurally different heart diseases. Spontaneous ventricular tachyarrhythmias (VT) from implantable cardio-defibrillators (ICD) are studied to explore clinical differences between CAD and DCM. Methods: The analysis is focused on: number of VT episodes, variability of the VT onset(More)
Aim: This study investigates circadian distribution of ventricular tachyarrhythmias (VT) in coronary artery disease (CAD) and dilated cardiomyopathy (DCM) patients that received an implantable cardioverter defibrillator (ICD) as secondary prevention. Methods: 37 patients are studied. Times of VT episode are retrieved from data log of the ICD; the analysis(More)
Aim of this paper is to propose a new parameter, based on 24-hour holter recording, that quantifies abnormal ventricular activity by calculating the peak ectopic rate (PEAK_ER) of every patient. This parameter is tested on a population of 200 heart failure (HF) patients in sinus rhythm (age (median [interquartile range]): 54 years [47-58], ejection fraction(More)
This explorative study focuses on differences between the onset of spontaneous ventricular tachyarrhythmias (VT) of patients with implantable cardioverter defibrillator (ICD) and affected by coronary artery disease (CAD) or dilated cardiomyopathy (DCM). From 57 patients (40 CAD and 17 DCM), 35 (24 CAD and 11 DCM) we retrieved a total of 154 spontaneous VTs(More)
Aim: This work investigates the correlation between the cardiac electrical activity underlying spontaneous ventricular tachyarrhythmias and their modes of onset. Signals: We analyzed 81 episodes of spontaneous ventricular tachycardia (VT) and ventricular fibrillation (VF) lasting at least 5 seconds from 17 patients. The cardiologist classified VT/VF(More)
We compared unenhanced and contrast-enhanced fast MRI and CT in the detection of liver metastases. Eleven patients with single or multiple hepatic lesions (42 in all) were submitted to CT and MR studies; T1- and T2-weighted TSE, T2-weighted TSE with fat suppression, unenhanced breath-hold TFE and early or delayed enhanced breath-hold TFE images were(More)
