Second-degree atrioventricular block.
1) While it is possible only one type of second-degree AV block exists electrophysiologically, the available data do not justify such a conclusion and it would seem more appropriate to remain a "splitter," and advocate separation and definition of multiple mechanisms, than to be a "lumper," and embrace a unitary concept. 2) The clinical classification of type I and type II AV block, based on pr...
متن کاملSecond-degree AV block.
Second-degree AV block includes a variety of conduction patterns of variable prognostic significance. Careful analysis of the pattern of PR and R-R intervals, the QRS axis and duration, as well as the presence or absence of structural heart disease should allow the medical director to assess the applicant's risk for life insurance.
متن کاملClassical and overconvergent modular forms
The purpose of this article is to use rigid analysis to clarify the relation between classical modular forms and Katz’s overconvergent forms. In particular, we prove a conjecture of F. Gouvêa [G, Conj. 3] which asserts that every overconvergent p-adic modular form of sufficiently small slope is classical. More precisely, let p > 3 be a prime, K a complete subfield of Cp, N be a positive integer...
متن کاملWhitney Forms of Higher Degree
Low order Whitney elements are widely used for electromagnetic field problems. Higher order approximations are receiving increasing interest but their definition remains unduly complex. In this paper we propose a new simple construction for Whitney p-elements of polynomial degree higher than one that use only degrees of freedom associated to p-chains. We provide a basis for these elements on si...
