Comparative study of pyroelectric response of PZT-film/Si, PZT-film/Por-Si/Si and PVDF-film/Si structures [PDF]

open access: yesarXiv, 2004
The comparative investigation of pyroelectric response modulation frequency dependences of structures of "polar active film-Si substrate" type based on PZT and PVDF and of structures of "polar active film - buffer layer - Si substrate" type based on PZT and porous silicon (por-Si) has been carried out.

Pré-excitação ventricular como causa de disfunção ventricular esquerda parcialmente reversível com ablação da via anômala.

open access: yesJournal of Cardiac Arrhythmias, 2020
A pré-excitação ventricular é causa rara de cardiomiopatia induzida ou mediada por arritmias. As vias acessórias à direita, especificamente com padrão de bloqueio de ramo esquerdo podem causar disfunção ventricular, pela ativação ventricular anormal ...

Standard Examples as Subposets of Posets [PDF]

open access: yesarXiv, 2013
We prove that a poset with no induced subposet $S_k$ (for fixed $k\geq 3$) must have dimension that is sublinear in terms of the number of elements.

Combined epicardial and endocardial substrate mapping and radiofrequency catheter ablation for ventricular tachycardia in chronic chagasic cardiomyopathy [PDF]

open access: yes, 2009
Background: Slow conduction scarred areas are related with ventricular tachycardia (VT) arrhythmogenesis in nonischemic cardiomyophathy. The purpose of this study was to characterize the substrate in both epicardial and endocardial surfaces of the left ...

Síndrome de Wolff-Parkinson-White e seus Possíveis Tratamentos em Pediatria: Uma Revisão Integrativa [PDF]

open access: yes
Introduction: Wolff-Parkinson-White (WPW) syndrome is a congenital cardiac condition of preexcitation due to the presence of one or more accessory pathways that connect the atrial myocardium to the ventricular myocardium, allowing reentry mechanisms that

Congenital left ventricular apical aneurysm presenting as ventricular tachycardia

open access: yesRevista Portuguesa de Cardiologia, 2016
The authors present the case of a 34-year-old male patient seen in our department due to palpitations. On the electrocardiogram monomorphic ventricular tachycardia (VT) was documented, treated successfully with amiodarone. The subsequent study revealed a
