This is a single-arm, non-randomized, non-blinded study designed to collect device data in patients with permanent His bundle (HB) pacing lead and an existing Abbott permanent pacemaker, defibrillator, or cardiac resynchronization device. Prospective data collection includes surface electrocardiograms, intracardiac electrograms, and pacing parameters, recorded during a patient visit. Additional retrospective data collection includes procedural data during the HB pacing lead and device implant.
Up to 200 subjects will participate in this clinical investigation. The clinical investigation will be conducted at up to 8 centers worldwide.
The total duration of the clinical investigation is expected to be 1 year, including enrollment and data collection from all subjects.

The purpose of this study is to determine which of 4 lead positions is most effective for pacemaker patients with Sick Sinus Syndrome in order to avoid development of atrial fibrillation.
The purpose of this study is to determine the incidence of atrial fibrillation and heart failure in patients with pacemaker therapy with different pacing modes (AAI, DDD, and a novel algor...
This study evaluates the acute effects of heart rate (HR) change on central hemodynamic parameters noninvasively.

Sick sinus syndrome (SSS) is associated with loss of HCN4 (hyperpolarization-activated cyclic nucleotide-gated potassium channel 4) function in the cardiac conduction system. The underlying mechanism ...
We present two cases with unexpected long sinus arrest resulting in syncope. There were no signs or symptoms of either sick sinus syndrome or increased vagal tone before the occurrence of pauses in th...

A cross-sectional study was conducted to assess the prevalence of sick building syndrome symptoms and its associated factors among bank employees. Data were collected through a self-administered MM040...
A condition caused by dysfunctions related to the SINOATRIAL NODE including impulse generation (CARDIAC SINUS ARREST) and impulse conduction (SINOATRIAL EXIT BLOCK). It is characterized by persistent BRADYCARDIA, chronic ATRIAL FIBRILLATION, and failure to resume sinus rhythm following CARDIOVERSION. This syndrome can be congenital or acquired, particularly after surgical correction for heart defects.
Systematic gathering of data for a particular purpose from various sources, including questionnaires, interviews, observation, existing records, and electronic devices. The process is usually preliminary to statistical analysis of the data.
First-released version of study results in a series of data collection efforts used for the purpose of generating further interest in and or funding of a research study.
Sampling of blood levels of the adrenocorticotropic hormone (ACTH) by withdrawal of blood from the inferior petrosal sinus. The inferior petrosal sinus arises from the cavernous sinus and runs to the internal jugular vein. Sampling of blood at this level is a valuable tool in the differential diagnosis of Cushing disease, Cushing syndrome, and other adrenocortical diseases.
