Vasovagal tonus index in dog with myxomatous mitral valve disease

Pesqui. vet. bras; 37 (10), 2017
The vasovagal tonus index (VVTI) is a useful and assessable index, obtained from standard ECG recordings, that is used to estimate heart rate variability (HRV), and may provide valuable information regarding the likelihood of progression into congestive heart failure (CHF). In this paperwork, we investig...

Cardio-oncologia na população pediátrica

Nas últimas décadas, a oncologia pediátrica tem demonstrado expressivo sucesso no tratamento do câncer infantojuvenil, com significativo aumento das taxas de cura e sobrevida, principalmente devido ao diagnóstico precoce e à quimioterapia mais eficaz, além do auxílio da radioterapia em determinad...

Manejo a longo prazo dos sobreviventes

A melhora dos resultados do tratamento oncológico com consequente aumento na sobrevida dos pacientes fez surgir um grupo chamado de sobreviventes. A incidência aumentada de doença cardiovascular nessa população é responsável por morbidade e mortalidade significativas a longo prazo. Este estudo é ...

Inducción de taquicardia reentrante nodal aurículo-ventricular por aplicación de radiofrecuencia
Induction of atrioventricular nodal reentrant tachycardia by radiofrequency application

Medicina (B.Aires); 77 (5), 2017
La taquicardia reentrante nodal aurículo ventricular es la forma más común de taquicardia sostenida, regular con QRS angostos. Fisiopatológicamente está determinada por una anatomía y fisiología nodal aurículo ventricular dual, con una vía rápida y otra lenta que forman el sustrato de la reentr...

The effects of cigarette smoking on ventricular repolarization in adolescents

Einstein (Säo Paulo); 15 (3), 2017
ABSTRACT Objective To assess the association between cigarette smoking and ventricular arrhythmias in adolescents. Novel electrocardiographic parameters -Tp-e interval, as well as Tpe/QT and Tpe/QTc ratios - were used to make this assessment. Methods The study population consisted of 87 subjects aged...

Evaluación de cardiología normal y patológica. Sistemas que utilizan la ley de Zipf-Mandelbrot
Evaluation of normal and pathological cardiac systems using the Zipf-Mandelbrot law

Prensa méd. argent; 103 (9), 2017
Introducción: con base en la ley de Zipf-Mandelbrot, fue desarrollado un método capaz de evaluar la complejidad de los sistemas cardiacos y diferenciar normalidad de enfermedad aguda. Objetivo: corroborar la utilidad y capacidad diagnóstica de la metodología fundamentada en la ley de Zipf-Mandelbrot ...

Single Derivation Fragmented QRS Can Predict Poor Prognosis in Successfully Revascularized Acute STEMI Patients

Arq. bras. cardiol; 109 (3), 2017
Abstract Background: QRS fragmentation (fQRS) is classically defined as the presence of slurred QRS morphology in at least two contiguous leads, and its prognostic importance has been shown in ST elevation myocardial infarction (STEMI). However, no study has investigated the significance of single lead ...

Reproducibility and Reliability Of QTc and QTcd Measurements and Their Relationships with Left Ventricular Hypertrophy in Hemodialysis Patients

Arq. bras. cardiol; 109 (3), 2017
Abstract Background: Left ventricular hypertrophy (LVH) is very common in hemodialysis patients and an independent risk factor for mortality in this population. The myocardial remodeling underlying the LVH can affect ventricular repolarization causing abnormalities in QT interval. Objective: to evaluat...
