Convergent atrial fibrillation ablation involves extensive epicardial as well as endocardial ablation of the left atrium. We examined whether it changes the morphology of the surface P wave. We reviewed electrocardiograms of 29 patients who underwent convergent ablation for atrial fibrillation. In leads V1, II and III, we measured P wave duration, area and amplitude before ablation, and at 1, 3...

Atrial Fibrillation (AF) ablation procedures have become a common place in clinical practice. Specifically, targeting both paroxysmal and persistent AF with ablation procedures has yielded relatively good success rates and outcomes. Various strategies have been employed to achieve the desired results. These have included various forms of energies such as RF, cryo and Laser. Also, hybrid converg...

In this note we consider a large step modiication of the Mizuno-Todd-Ye O(p nL) predictor-corrector interior-point algorithm for linear programming. We demonstrate that the modiied algorithm maintains its O(p nL)-iteration complexity, while exhibiting superlinear convergence for general problems and quadratic convergence for non-degenerate problems. To our knowledge, this is the rst constructio...

and Applied Analysis 3 where σ s σ σj−1 s . In this case, we write σ − limx . By V 2 σ , we denote the set of all σ-convergent and bounded double sequences. One can see that in contrast to the case for single sequences, a convergent double sequence need not be σ-convergent. But every bounded convergent double sequence is σ-convergent. So, c∞ 2 ⊂ V 2 σ ⊂ ∞ 2 . In the case σ i i 1, σ-convergence ...

Let M ⊂ C be a minimal real-analytic CR-submanifold and M ′ ⊂ C ′ a realalgebraic subset through points p ∈ M and p ∈ M , N, N ′ ≥ 2. We show that that any formal (holomorphic) mapping f : (C , p) → (C ′ , p), sending M into M , can be approximated up to any given order at p by a convergent map sending M into M . If M is furthermore generic, we also show that any such map f , that is not conver...

In this paper we prove several new characterizations of weakly unconditionally Cauchy series in Banach spaces and in the dual space of a normed space. For a given series ζ, we consider the spaces S(ζ), Sw(ζ) and S0(ζ) of bounded sequences of real numbers (ai)i such that the series P i aixi is convergent, weakly convergent or ∗-weakly convergent, respectively. By means of these spaces we charact...

For sequences of fuzzy numbers, Nanda 1 studied the sequences of fuzzy numbers and showed that the set of all convergent sequences of fuzzy numbers forms a complete metric space. Kwon 2 introduced the definition of strongly p-Cesàro summability of sequences of fuzzy numbers. Savaş 3 introduced and discussed double convergent sequences of fuzzy numbers and showed that the set of all double conve...
