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...
Abstract Background: Little has been studied on heart rate and its relationship with metabolic disorders. Objective: To identify possible association between heart rate (HR) and metabolic disorders in children and adolescents. Methods: This cross-sectional study evaluated 2.098 subjects, aged between ...
RESUMO Objetivo: Investigar a associação entre parâmetros de variabilidade da frequência cardíaca (VFC) e atividades físicas de lazer e deslocamento em adolescentes do sexo masculino. Métodos: A amostra incluiu 1.152 adolescentes do sexo masculino com idades entre 14 e 19 anos. A variação do...
Abstract Warm-up is broadly used to increase performance and protect against injury in sports. However, the effects of different models of warm-up on maximal exercise and the subsequent recovery period are undetermined. This study aimed to assess the effects of different warm-ups on performance, blood pr...
O objetivo deste estudo foi avaliar os efeitos da ventilação não invasiva (VNI) por pressão positiva contínua nas vias aéreas (Continuos Positive Airway Pressure - CPAP) e por pressão positiva em dois níveis (Bilevel Positive Airway Pressure - BiPAP) sobre a demanda miocárdica no pós-operatóri...
Abstract Purpose: To determine if the combination of lidocaine with epinephrine or gamma globulin would decrease the rate or reduce the amount of local absorption of lidocaine through the airway. Methods: Twenty adult male cats were randomly and evenly distributed into four groups: 1) Group LG: lidoca...
Abstract Objective: To evaluate a possible evolutionary post-heart transplant return of autonomic function using quantitative and qualitative information from recurrence plots. Methods: Using electrocardiography, 102 RR tachograms of 45 patients (64.4% male) who underwent heart transplantation and that...
El objetivo de esta investigación es obtener una ecuación para determinar VO2 máx. a través de una prueba submáxima utilizando la frecuencia cardíaca de recuperación (FCr). Se diseñó en un estudio descriptivo correlacional dentro de un marco cuantitativo y se evalu...
Abstract Background and objectives: The Analgesia Nociception Index is an index used to measure the levels of pain, sympathetic system activity and heart rate variability during general anesthesia.
