Abstract COVID-19 is a predominantly respiratory disease, but it has increasingly been characterized by systemic, extrapulmonary involvement. The spectrum of virus infection can vary from person to person with very mild and non-respiratory symptoms to severe acute respiratory disease, sepsis with organ dysfunction and death. The virus responsible for COVID-19 is transmitted between people mainly through respiratory droplets and contact routes. The use of a face mask by the infected person, symptomatic or asymptomatic, decreases the elimination of the virus […]

ABSTRACT Physical activity (PA) has several healthy effects, such as preventing chronic diseases and reducing mortality. However, 27.5% and 47% of the world’s and Brazilian’s adult population, respectively, do not reach the minimum recommended PA amount according to the latest guidelines. It has recently been observed that even lower than the recommended doses of PA promote health benefits. This information can be very useful as low-dose PA may be more feasible to achieve by a larger part of the population, […]

ABSTRACT Atrioventricular (AV) blocks are rarely observed in exercise test (ET), specially during the effort phase. There are few data available about exercise-induced AV blocks in specific guidelines or textbooks, which was the reason for this article. This is a narrative literature review with the aim of describe the physiological basis of the AV conduction during exercise and the possible mechanisms involved in the exercise-induced AV block genesis, as well as their prognostic implications. Moreover, the authors emphasize the importance […]
