Filter by:This study investigates the impact and safety of wireless monitoring on the prognosis of heart failure patients with implanted pacemakers and defibrillators. It aims to examine the frequency of unplanned early hospital visits and the early diagnosis/intervention of disease exacerbation based on the presence or absence of wireless monitoring. Additionally, the study analyzes the influence of wireless monitoring on the patient's disease progression as well as satisfaction of the study participants.
Atrial fibrillation (AF) is a common cardiac arrhythmia that leads to increased risk of heart failure, hospitalization, thromboembolic events, and death. Restoration of normal heart rhythm is performed in many patients with AF to improve symptoms. In this study, the investigators will consider patients who fail 2 or more trials of DC cardioversion as having refractory AF. The aim of this study is to assess whether the use of double sequential defibrillation in patients with refractory AF has a higher success rate in reverting them to a normal heart rhythm than a third cardioversion. This is a phase III, randomized controlled, single-centered, superiority trial. All patients with AF admitted to the coronary care unit (CCU) for DC cardioversion, and refractory to at least two trials of DC cardioversion will be enrolled. Patients are randomized into two arms: the first will receive a third trial of DC cardioversion (standard of care) and the second will receive double sequential external defibrillation. The resolution of AF by reverting back to normal sinus rhythm is the primary outcome of the investigators. This will be determined using EKG (electrocardiogram) immediately after DC cardioversion or double sequential defibrillation.
All patients having an implantable cardiac defibrillator (ICD) implanted and having follow-up at the Cantonal Hospital Lucerne (LUKS), the investigator center, are included in this retrospective ICD lead registry from 2006 onwards. Data is collected prospectively from december 2016 onwards. After certain ICD-leads tended to fail early the investigators aimed for a registry monitoring our patient population with defibrillator leads and evaluating their long-term performance.
