The purpose of this study is to determine if patients implanted with a St. Jude Medical (SJM) implantable cardioverter defibrillator (ICD) will benefit by using AutoIntrinsic Conduction Search (AICS) rather than only a programmed AV/PV delay. This study will compare the two methods of programming with respect to intrinsic activity.

The purpose of this study is to characterize performance of the MARVEL algorithm downloaded into the MicraTM TPS to provide atrial synchronous ventricular pacing in subjects with AV block.
In case of sinus node dysfunction, it is often necessary to choose the safer option provided by a DDD pacemaker even though the most appropriate mode of pacing is AAI mode. In addition to...
This study is a long-term, prospective, and controlled evaluation of the incidence of persistent atrial fibrillation (AF) in patients with severe intra-right atrial conduction delay paced ...
Examination of the bone conduction of persons which according to the pure tone audiogram have a normal age related hearing threshold in the air conduction.
This study aims to describe in depth the CNS, CNS HIV reservoir and CNS viral rebound in consenting SEARCH 019 subjects prior to, during and after the SEARCH 019 study intervention (VHM + ...
The Annual Crop Planning (ACP) problem was a recently introduced problem in the literature. This study further expounds on this problem by presenting a new mathematical formulation, which is based on ...
In the re-evaluated paper, Xie et al. proposed a new fast search algorithm for vector quantization encoding, which optimized the priority checking order of variance and norm inequality in order to spe...
Increased maternal serum bile acid concentrations in intrahepatic cholestasis of pregnancy (ICP) are associated with fetal cardiac arrhythmias. Ursodeoxycholic acid (UDCA) has been shown to demonstrat...
Obstetrician-gynecologists often are the sole providers of health care to female patients. Because cardiovascular disease is the leading cause of death in women in the United States, obstetrician- gyn...
One of the ANTI-ARRHYTHMIA AGENTS, it blocks SODIUM CHANNELS and slows conduction within the His-Purkinje system and myocardium.
Agents used for the treatment or prevention of cardiac arrhythmias. They may affect the polarization-repolarization phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibers. Anti-arrhythmia agents are often classed into four main groups according to their mechanism of action: sodium channel blockade, beta-adrenergic blockade, repolarization prolongation, or calcium channel blockade.
A potent anti-arrhythmia agent, effective in a wide range of ventricular and atrial arrhythmias and tachycardias. Paradoxically, however, in myocardial infarct patients with either symptomatic or asymptomatic arrhythmia, flecainide exacerbates the arrhythmia and is not recommended for use in these patients.
Transmission of sound waves through vibration of bones in the SKULL to the inner ear (COCHLEA). By using bone conduction stimulation and by bypassing any OUTER EAR or MIDDLE EAR abnormalities, hearing thresholds of the cochlea can be determined. Bone conduction hearing differs from normal hearing which is based on air conduction stimulation via the EAR CANAL and the TYMPANIC MEMBRANE.
Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the SINOATRIAL NODE and the right atrium (SA block) or between atria and ventricles (AV block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.
