The aim of the study is the comparison of two different leads in their capabilities to detect episodes and duration of paroxysmal atrial fibrillation (AF) and atrial tachyarrhythmia (AT), and the rejection of far field sensing of the far field R-wave (FFRW).
The aim of the study is the comparison of two different leads in their capabilities to detect episodes and duration of paroxysmal AF and AT and the rejection of far field sensing of the far field R-wave (FFRW). The study aims to evaluate the accuracy of the detection of atrial tachyarrhythmias (ATAs). An improved detection can potentially increase the accuracy of clinical treatment decisions, based on device derived data.

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.
Hypothesis Treatment with rate adaptive single chamber atrial pacing (AAIR) reduces the risk of death compared with rate adaptive dual chamber pacing (DDDR) in patients with sick sinus syn...
1. Background - Pacemaker treatment gives asynchronous activation of the heart that often results in decreased heart function and clinical heart failure. New pacemaker types that...
Although arrhythmias are frequent in patients with Takotsubo syndrome (TTS), data on sick sinus syndrome remain elusive. Here, we report a case of TTS initiated by a seizure as a physical trigger that...
To study association of rs6795970 polymorphism of SCN10A gene with development of idiopathic sick sinus syndrome (ISSS).
Residual fibrous structures, referred as "ghosts", are occasionally encountered following lead extraction. Though typically detected in patients with cardiac device infections, their prognostic and th...
A 49-year-old man presented with a 1-week history of right facial paraesthesia with blurred vision and diplopia. Examination was normal apart from reduced facial sensation. Following appropriate neuro...
The case of a 59-year-old woman who underwent endoscopic sinus surgery for right maxillary sinusitis 5 years before visiting our otorhinolaryngologic department complaining of right-sided facial depre...
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.
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.
An absence from work permitted because of illness or the number of days per year for which an employer agrees to pay employees who are sick. (Webster's New Collegiate Dictionary, 1981)
Air-filled spaces located within the bones around the NASAL CAVITY. They are extensions of the nasal cavity and lined by the ciliated NASAL MUCOSA. Each sinus is named for the cranial bone in which it is located, such as the ETHMOID SINUS; the FRONTAL SINUS; the MAXILLARY SINUS; and the SPHENOID SINUS.
An idiopathic syndrome characterized by the formation of granulation tissue in the anterior cavernous sinus or superior orbital fissure, producing a painful ophthalmoplegia. (Adams et al., Principles of Neurology, 6th ed, p271)
