1. O que é a Síndrome de Wolff-Parkinson-White?
A síndrome de Wolff-Parkinson-White (WPW) é uma doença congênita gerando taquicardias e arritmias, que reduzem a eficiência do coração. As manifestações clínicas incluem sudorese, dor no peito, cefaleia, dificuldades respiratórias, letargia, sensação de desmaio, perda de apetite, palpitações rápidas e visíveis no tórax, incluindo insufic

2. Prognostic Value of T-wave Positivity in Lead aVR in COVID-19 Pneumonia
SUMMARY OBJECTIVE: T-wave positivity in the lead aVR is a marker of ventricular repolarization abnormality and provides information on short- and long-term cardiovascular mortality in heart failure patients, those with anterior myocardial infarction, and patients who underwent hemodialysis for various reasons. The aim of this study was to investigate the re

3. Impact of Air Pollutant on Heart Rate Variability in Healthy Young Adults
Abstract Background: Air pollution and sex independently affect cardiac autonomic control, which can be assessed by heart rate variability (HRV). The research hypothesis is that individuals exposed to low concentrations of pollution have higher cardiac autonomic modulation compared to those exposed to high concentrations and that women have better cardiac a

4. A randomized clinical trial on inhaled ciclesonide for managing acute asthma in the emergency room
ABSTRACT BACKGROUND: Use of inhaled corticosteroids for managing acute asthma exacerbations has been tested since the 1990s. OBJECTIVE: To compare high doses of inhaled ciclesonide with systemic hydrocortisone for managing acute asthma exacerbations in the emergency department. DESIGN AND SETTING: Double-blind, randomized clinical trial in the public heal

5. Implementation of a Telecardiology Service in a Health Unit in the City of Porto Alegre, Brazil: A Pilot Study
Abstract Background: The implementation of Telecardiology in primary care in the city of Porto Alegre, Brazil, is a viable and promising strategy. It would decrease the distance between patient and specialized professional services by reducing unnecessary referrals and improving the quality of primary care and satisfaction of patients and health professiona

6. Logic Analysis of Arrhythmia Triggered by Pacemaker Special Functions - An Educational Presentation
Abstract Dual-chamber pacemaker is a fully automatic pacemaker with the function of simulating human physiological pacing. It regulates pacing by programming different refractory periods and various special functions, which are closely related to arrhythmia. After in-depth understanding of these special functions, regular electrocardiogram follow-up analysis

7. Index of cardiac-electrophysiological balance and the effects of thrombolytic therapy on the electrocardiogram of patients with pulmonary embolism
RESUMO OBJETIVO: Diferentes parâmetros de eletrocardiograma (ECG) têm sido investigados para predizer mortalidade e arritmia em pacientes com embolia pulmonar aguda (EPA). O efeito agudo da terapia trombolítica (TT) nesses parâmetros ainda não foi investigado. MÉTODOS: Examinamos os dados de 83 pacientes avaliados com EPA de alto risco e que recebera

8. Electrocardiographic Abnormalities in Hypertension Models
Abstract Background: Hypertensive condition can lead to abnormalities in heart structure and electrical activity. The electrocardiogram (ECG) is a recording of the electrical activity of the heart and widely used to diagnose and detect heart problem. Objective: We conducted a comparative ECG analysis between two hypertension models (L-NAME and SHR) and the

9. Hepatic Elastography in the Assessment of Heart Failure: Where We Came from and Where We Are Going
Abstract Background: Stress test is used to detect coronary artery disease (CAD). The QTc interval dispersion (dQTc) is an electrocardiographic index of ventricular repolarization heterogeneity. Some researchers have linked transient myocardial ischemia induced by physical exertion with increased heterogeneity of ventricular repolarization measured by dQTc.

12. Association between heart rate, heart rate variability, cortisol, glucose and electrolytes in healthy newborn calves
RESUMO Este estudo teve como objetivo avaliar os efeitos dos níveis de eletrólitos, glicose e cortisol sobre a frequência cardíaca (FC) e a variabilidade da frequência cardíaca (VFC) em bezerros recém-nascidos e saudáveis. Dezessete bezerros da raça Holandesa foram avaliados durante o primeiro mês de vida e foram analisadas as concentrações plasm
