Objetivo: describir los hallazgos en el Holter 24 horas (H24H) y la prueba de mesa bas-culante (PMB) en pacientes con situación pos-COVID-19 (SPC) y explorar su asociación con los síntomas.Metodología: estudio transversal descriptivo en el que se incluyeron 83 pacientes en SPC con H24H o PMB. Mediant...
Abstract Introduction: It is challenging to diagnose syncope in patients with pacemakers. Because these patients have increased morbidity and mortality risks, they require immediate attention to determine the causes in order to provide appropriate treatment. This study aimed to investigate the causes an...
Abstract Syncope in pediatrics represents an important cause of visits to the emergency units. For this reason, excluding a cardiac or malignant origin is essential at the time of the initial approach to determine what is the next step in management, or if they need to be referred to a pediatric cardiolo...
Abstract Objective The present study aimed to analyze cardiac autonomic modulation via spectral and symbolic analysis of heart rate variability (HRV) in women with polycystic ovary syndrome (PCOS) who were subjected to two consecutive tilt tests. Methods A total of 64 women were selected and divided in...
Abstract Background Vasovagal syncope (VVS) is a frequent clinical condition in which a genetic background seems to be implicated. Considering that the adrenergic receptors (ARs) may play a role in VVS, the present study has as principal aim to determine if the α- and β-AR (ADRA and ADRB) gene...
Objetivo: Valorar los resultados de las pruebas de inclinación realizadas en un lapso de 2 décadas. Métodos: Este es un estudio observacional, descriptivo y retrospectivo. Se analizaron los resultados de las Pruebas de Inclinación (PI) realizadas entre 1997 y 2018 en forma consecutiva por una sola pe...
Abstract Background: Maintenance of orthostatism requires the interaction of autonomic and muscle responses for an efficient postural control, to minimize body motion and facilitate venous return in a common type of syncope called neurocardiogenic syncope (NCS). Muscle activity in standing position may ...
Resumen Introducción: Es frecuente de encontrar personas enviadas para realizar la prueba de Tilt Test (TT), que sufrieron un solo síncope aislado o que ocurre muy ocasionalmente durante su vida. En este trabajo nos preguntamos en qué se diferencian estas personas de las que nunca tienen síncopes. ...
Abstract Background: Cardioinhibitory vasovagal response is uncommon during the tilt test (TT). Heart rate variability (HRV) by use of spectral analysis can distinguish patients with that response. Objective: To compare the HRV in patients with cardioinhibitory vasovagal syncope (case group - G1) with ...
