The purpose of this registry study is to collect information about routine clinical practices with device implantation to treat bradycardia and cardiac systolic dysfunction (heart rhythm disorders) across global centers of excellence in cardiac pacing. In particular, this study will examine the use of conduction system pacing (CSP) in clinical practice. Information collected in the registry will help researchers better characterize strengths and limitations of current technology and treatments.
