INTRODUCTION AND OBJECTIVES Permanent His-bundle pacing is effective in patients with supra-Hisian atrioventricular block. We report our experience in patients with infra-Hisian atrioventricular block. METHODS The study involved selected patients referred for syncope and intraventricular conduction disturbance, infra-Hisian atrioventricular block, with left ventricular dyssynchrony and no cor...

Assimilation of crustal rocks by mafic magmas is considered important for the formation of sulfide ores. Radiogenic isotope systems may allow one to quantify the amount of contamination and to distinguish between possible contaminants. We have studied Sm-Nd, Rb-Sr, and U-Pb isotope systems in two mafic intrusions of the Nain Plutonic Suite: the 1333 Ma Voisey’s Bay intrusion that hosts the majo...

The lunar meteorites have valuable informations for understanding the evolution of the Moon’s crust, because each meteorite may potentially provide a new insight into the thermal history of unexplored regions of the Moon. In spite of their scientific interests, chronological studies of Very-Low-Ti (VLT) basaltic meteorites have not be well understood, since the most VLT basalt meteorites are br...

A seemingly harmless reordering of the steps in a block Gibbs sampler can actually lead to change invariant distribution. It is shown that, despite altered distribution, “out-of-order” converges at same rate as original Markov chain.

introduction abnormal neural impulses in the nervous system may lead to various diseases and disabilities. high frequency alternating currents (hfac) has been used to block the propagation of such impulses and improve the symptoms or disabilities. the technique is safe, reversible, and relatively selective, and its reliability, the optimum stimulation parameters, and elimination of the onset re...

BACKGROUND Ensuring a haemodynamically effective cardiac rhythm is a challenge in patients waiting for pacemaker reimplantation after transcutaneous lead extraction due to an infection of the implanted system. AIM The authors report a retrospective analysis of temporary pacing with an active fixation lead (AFTP) connected to an externalised pacemaker in patients after transvenous lead extract...

Nanoscale analysis may be used to design new types of mucoadhesive polymers. Understanding of the surface interactions between hydrophilic polymer surfaces and mucins can lead to improved adhesive bonding by hydrogen bonding. Alternatively, decoration of a mucoadhesive polymer surface with tethers of linear and block copolymers containing neutral or ionizable structures provides increased inter...

Reenements of Sanov's large deviations theorem lead via Csiszz ar's information theoretic identity to reenements of the Gibbs conditioning principle which are valid for blocks whose length increase with the length of the conditioning sequence. Sharp bounds on the growth of the block length with the length of the conditioning sequence are derived. Extensions of Csiszz ar's triangle inequality an...

Complex cyanotic congenital heart diseases with left isomerism are sometimes associated with atrioventricular nodal conduction disturbances that may need permanent pacing. Surgical palliation in such anatomy connecting the superior vena cava to the pulmonary artery precludes a transvenous access for an endocardial pacing lead to the ventricles. Epicardial leads in these patients fail if the pac...
