Neuromuscular Electrical Stimulation on Hemodynamic and Respiratory Response in Patients Submitted to Cardiac Surgery: Pilot Randomized Clinical Trial

Neuromuscular electrical stimulation seems to be a promising option to intensify the rehabilitation and improve the exercise capacity of patients in the immediate postoperative period of cardiac surgery. Objective: This study aimed to evaluate the hemodynamic (heart rate, systolic blood pressure, diasto...

Increased Left Atrial Volume and Its Relationship to Vitamin D in Primary Care

The study is based on the fact that left atrial (LA) volume measurement is a marker of the presence of diastolic dysfunction and that Vitamin D deficiency may be associated with ventricular remodeling, worsening of left ventricular (LV) diastolic and systolic function, and activation of the renin-angiote...

Evaluation of cardiac autonomic modulation using symbolic dynamics after cardiac transplantation

Abstract Objective: To characterize the behavior of cardiac autonomic modulation in individuals with different times after orthotopic heart transplantation (HTx) using symbolic dynamics analysis. Methods: Sixty patients were evaluated after HTx. We recorded their instantaneous R-R intervals (RRi) by ca...

The factors affecting rhythm control for cryoablation of atrial fibrillation in mitral valve surgery

Abstract Objective: To evaluate the factors impacting on the conversion to sinus rhythm and on the postoperative rhythm findings in the six-month follow-up period of a mitral valve surgery combined with cryoablation Cox-Maze III procedure, in patients with atrial fibrillation. Methods: In this study, w...

Introduction of Application of Gini Coefficient to Heart Rate Variability Spectrum for Mental Stress Evaluation

Arq. bras. cardiol; 113 (4), 2019
Abstract Background: The Gini coefficient is a statistical tool generally used by economists to quantify income inequality. However, it can be applied to any kind of data with unequal distribution, including heart rate variability (HRV). Objectives: To assess the application of the Gini coefficient to ...

Avaliação do comportamento cardiovascular de gestantes durante o repouso e na fase de relaxamento de um protocolo aquático terapêutico de moderada intensidade

Fisioter. Bras; 20 (4), 2019
Objetivo: Avaliar o comportamento cardiovascular de gestantes, durante o repouso e fase de relaxamento de um protocolo aquático terapêutico de moderada intensidade. Métodos: Foram estudadas 10 gestantes, com média de 21,8 ± 4,0 semanas de gestação. Antes e após o protocolo foram aferidas a pressÃ...

Effects of high-intensity interval training compared to moderate-intensity continuous training on maximal oxygen consumption and blood pressure in healthy men: A randomized controlled trial

Biomédica (Bogotá); 39 (3), 2019
Abstract Introduction: Aerobic exercise generates increased cardiorespiratory fitness, which results in a protective factor for cardiovascular disease. High-intensity interval training (HIIT) might produce higher increases on cardiorespiratory fitness in comparison with moderate-intensity continuous tra...

Respostas autonômicas de recém-nascidos prematuros ao posicionamento do corpo e ruídos ambientais na unidade de terapia intensiva neonatal

RESUMO Objetivo: Avaliar as respostas fisiológicas e do sistema nervoso autônomo de recém-nascidos prematuros ao posicionamento do corpo e ruídos ambientais na unidade de terapia intensiva neonatal. Métodos: Este foi um estudo quasi-experimental. O sistema nervoso autônomo de recém-nascidos foi ...

Saturación de oxígeno, frecuencia cardiaca y respiratoria en recién nacidos a término en poblaciones de altura
Oxygen saturation, heart and respiratory frequency of term newborns in high-altitude populations

Rev. cuba. pediatr; 91 (3), 2019
Introducción: La adaptación a la vida extrauterina de los recién nacidos es importante, especialmente en poblaciones de altura donde las características son diferentes a poblaciones a nivel del mar. Objetivos: Determinar la correlación entre saturación de oxígeno, frecuencia cardiaca y respirato...
