About this study
Official title: Study of the Efficacy and Safety of Cardiac Pacing of 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.
