Schematic diagram of an alternate possible mechanism in the Lown-Ganong-Levine syndrome. The impulse from the sinoatrial node (SAN) arrives either via the posterior internodal tract (PIT) or the normal tract to the atrioventricular node (AVN) at a His-Purkinje junction (LAMBDA) distal to the recording site of the His electrode. Retrograde depolarization of the proximal, and antegrade depolariza...

Let k be a totally real field, and let A/k be an absolutely irreducible, polarized Abelian variety of odd, prime dimension whose endomorphism rings is non-trivial and is defined over k. Then the only strictly compatible families of abstract, absolutely irreducible representations of Gal(k/k) coming from A are tensor products of Tate twists of symmetric powers of two-dimensional λ-adic represent...

Let V be a p-adic representation of the absolute Galois group G of Qp that becomes crystalline over a finite tame extension, and assume p 6= 2. We provide necessary and sufficient conditions for V to be isomorphic to the p-adic Tate module Vp(A) of an abelian variety A defined over Qp. These conditions are stated on the filtered (φ,G)module attached to V . 2000 Mathematics Subject Classificatio...

Atrial fibrillation (AF) is the most common sustained arrhythmia in clinical practice, affecting slightly less than 1% of the general population. Patients with AF suffer from a decrease in functional capacity secondary to a combination of palpitations, dyspnea, myocardial ischemia, congestive heart failure and hypotension. In addition, unorganized atrial electrical and mechanical activity resul...

BACKGROUND Lown-Ganong-Levine syndrome, includes a short PR interval, normal QRS complex, and paroxysmal tachycardia. The pathophysiology of this syndrome includes an accessory pathway connecting the atria and the atrioventricular (AV) node (James fiber), or between the atria and the His bundle (Brechenmacher fiber). Similar features are seen in enhanced atrioventricular nodal conduction (EAVNC...

Syndrome de P -R court et QRS normal avec les crises de tachycardie Paroxystique ou le syndrome de (Lown-Ganong-Levine). Dans une enqete epidemiologique sur les ma­ladies cardiovasculaires chez deux populations rurales de Roudsar et Azarbaidjan oriental nous avons retrouve 6 cas de P -R court avec QRS normal. Dans cet article nous avons brievement passe en revue les vois de conduction auriculov...

Electrophysiologic study of a 55-year-old patient with Lown-Ganong-Levine syndrome associated with apical hypertrophic cardiomyopathy is reported. The patient had a history of recurrent attacks of tachyarrhythmia and his electrocardiogram showed a short P-R interval (0.10 sec) with narrow QRS complex and left ventricular hypertrophy with giant negative T waves. His cineangiogram showed severe a...

\s=b\Obesity has been documented to be an independent risk factor for sudden death and other cardiovascular mortality. The present study was designed to monitor and quantify cardiac arrhythmias in obese subjects with and without eccentric left ventricular hypertrophy, who were matched with regard to arterial pressure, age, sex, and height with lean subjects. Prevalence of premature ventricular ...
