Medtronic is sponsoring a quality improvement study called Brady MX. It is hypothesized that lack of awareness of treatment and diagnostics pathways result in lower number of referrals to implanters of IPG.

Hypothesis- Radiofrequency ablation, targeting the sympathetic input of the sinus node identified by 20Hz stimulation at the junction of the superior vena cava and the right atrium, will e...
Background: Sinus node dysfunction is a major cause of bradycardia necessitating pacemaker implantation. Evidences of genetic study supported that some genes involved in the pacemaker curr...
Optimal pacing strategy for patients with SND is still unknown, although several publications in the past years demonstrated a deleterious effect of ventricular pacing. However, pacing has...
To determine if dual chamber rate-modulated pacing (DDDR) in patients with sick sinus syndrome is superior to single chamber pacing (VVIR) with respect to subsequent frequency of adverse c...
The RESOLVE II Study will assess the safety and efficacy of the steroid-releasing S8 Sinus Implant when used in post-sinus surgery patients who present with recurrent sinus obstruction. Th...
Familial sick sinus syndrome is associated with gene mutations and dysfunction of ion channels. In contrast, degenerative fibrosis of the sinus node tissue plays an important role in the pathogenesis ...
Superior vena cava (SVC) is an important source of origin of atrial fibrillation (AF) triggers other than a pulmonary vein. Because of the proximity of SVC-aorta ganglionic plexi to the SVC and the ex...
The sinoatrial node (SAN) is the dominant pacemaker of the heart. Abnormalities in SAN formation and function can cause sinus arrhythmia, including sick sinus syndrome and sudden death. A better under...
The falcine sinus in the falx cerebri is rarely encountered in adults, appearings in approximately 2.1% of CT examinations of adult patients. Some authors have studied the plexus rather than the sinus...
The lymph node (LN) is an important immune system in which a number of antigen-presenting cells (APCs) are present that induce rapid immune responses to foreign antigens. While a great number of macro...
The omission of atrial activation that is caused by transient cessation of impulse generation at the SINOATRIAL NODE. It is characterized by a prolonged pause without P wave in an ELECTROCARDIOGRAM. Sinus arrest has been associated with sleep apnea (REM SLEEP-RELATED SINUS ARREST).
Irregular HEART RATE caused by abnormal function of the SINOATRIAL NODE. It is characterized by a greater than 10% change between the maximum and the minimum sinus cycle length or 120 milliseconds.
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.
Simple rapid heartbeats caused by rapid discharge of impulses from the SINOATRIAL NODE, usually between 100 and 180 beats/min in adults. It is characterized by a gradual onset and termination. Sinus tachycardia is common in infants, young children, and adults during strenuous physical activities.
A cardiac arrhythmia that is caused by interaction of two independently initiated cardiac impulses of different rates from two separate foci. Generally one focus is the SINOATRIAL NODE, the normal pacemaker. The ectopic focus is usually in the HEART VENTRICLE but can be in the HEART ATRIUM or the ATRIOVENTRICULAR NODE. Modulation of the parasystolic rhythm by the sinus rhythm depends on the completeness of entrance block surrounding the parasystolic focus.
