Time- and frequency-domain analysis of heart rate variability (HRV) has been proven effective in describing alteration of autonomic control mechanisms and in identifying patients with increased cardiac and arrhythmic mortality. Patients with implantable cardioverter defibrillators offer the opportunity to evaluate HRV patterns before ventricular tachycardia(More)
BACKGROUND Heart failure patients with implantable cardioverter-defibrillators (ICDs) or an ICD for resynchronization therapy often visit the hospital for unscheduled examinations, placing a great burden on healthcare providers. We hypothesized that Internet-based remote interrogation systems could reduce emergency healthcare visits. METHODS AND RESULTS(More)
PURPOSE The Medtronic CareLink allows remote implantable device follow-up. In this first European experience with CareLink, we assessed the ease of use of the system, the acceptance, and satisfaction of patients and clinicians. METHODS Patients implanted with biventricular defibrillators for more than 6 months received the CareLink monitor and were(More)
The aim of the present study is to evaluate if remote monitoring with the CareLink Network may improve clinical management of tachyarrhythmias and heart failure episodes in patients treated with biventricular defibrillators (CRT-D). Patients implanted with CRT-D for more than 6 months received the CareLink monitor and were trained to perform device(More)
BACKGROUND Launch of remote follow-up systems in Europe is currently underway. However, there is insufficient understanding of postimplant practices with respect to device follow-up, reprogramming of device features, and postshock clinic visits. METHODS We analyzed device-stored data from patients implanted with biventricular defibrillators (CRT-ICD) to(More)
BACKGROUND Heart failure patients with implantable defibrillators place a significant burden on health care systems. Remote monitoring allows assessment of device function and heart failure parameters, and may represent a safe, effective, and cost-saving method compared to conventional in-office follow-up. OBJECTIVE We hypothesized that remote device(More)
We evaluated the handling performance at implant, and the long-term atrial and ventricular electrical performance of a new generation using a very small surface area (1.2 mm2) steroid-eluting electrode (Medtronic CapSure Z). We compared the performance of CapSure Z to that of traditional passive fixation leads, with and without steroid elution. The study(More)
BACKGROUND Studies focusing on the effects of telemanagement programs for chronic heart failure (CHF) on functional status are lacking, and the prognostic value of the clinical response to the programs is unknown. In the Lombardy region of Italy, a home-based telesurveillance program (HTP) including multidisciplinary management and remote telemonitoring for(More)
OBJECTIVES To verify implementation and use of TELEMACO (TELEMedicina Ai piccoli COmunilombardi;, which provides specialized continuity of care with innovative healthcare services in remote areas of the Lombardy region of Italy; to design a network in the territory for sharing of continuityof- care programs; and to(More)
BACKGROUND Heart failure patients with implantable defibrillators (ICD) frequently visit the clinic for routine device monitoring. Moreover, in the case of clinical events, such as ICD shocks or alert notifications for changes in cardiac status or safety issues, they often visit the emergency department or the clinic for an unscheduled visit. These planned(More)
