View clinical trials related to Bradyarrhythmias.
Filter by:At present, cardiac pacing has been widely used in the treatment of bradyarrhythmias and heart failure, which can effectively improve the survival rate of patients. With the rapid development of technology, different sites can be chosen to pace, such as right atrial appendage, the atrial septum and the right atrial wall in the atrium, His bundle, left bundle branch area, right ventricular apex, outflow tract, and left ventricular pacing via coronary vein in the ventricle. There are few studies comparing the long-term efficacy and safety of different pacing sites in daily practice. This study aims to observe the efficacy and safety of cardiac pacing at different sites in short and long term, and to compare the advantages and disadvantages of pacing at different sites.
At present, cardiac pacing has been widely used in the treatment of bradyarrhythmias and heart failure, which can effectively improve the survival rate of patients. With the rapid development of technology, you can choose to pace the heart in different parts. The atrium can choose the right atrial appendage, the atrial septum and the right ventricular side wall. The right ventricle can choose to be paced in the His bundle, right ventricular apex and ventricular septal outflow tract. The right ventricle can choose the pacing positions including left bundle branch pacing and left ventricular pacing via coronary vein. There are few studies comparing the long-term efficacy and safety of different pacing programs in daily practice. This study is to observe the short-term and long-term effects and safety of different parts of cardiac pacing, and compare the advantages and disadvantages of different parts of cardiac pacing.
This is a large prospective registry of patients submitted to cardiac electronic devices implantation designed to investigate the incidence, risk factors and prognostic of thromboembolic complications associated with transvenous lead implantation.
Previous experimental and clinical studies have consistently suggested that right ventricular (RV) apical pacing has important adverse effects. Ventricular pacing, however, is required, and cannot be reduced in many patients with atrioventricular block. The SAFE-LVPACE study is a randomized controlled trial that compare the effects of conventional right ventricular (RV) pacing vs. left ventricular (LV) in patients with AV block.
