Abstract Since the 1990s, the hypothesis that reducing vagal action increased mortality in cardiac patients and healthy adults has been suggested. Based on this premise, studies came that evaluated the possibility of relating the reduction of HR in the phase of recovery of the exercise stress test (ET) with prognostic implication. This review aimed to perform a critical analysis of studies that evaluated the HR response after effort, and its correlation with cardiovascular outcomes. Pubmed’s virtual health library was available, […]

ABSTRACT Brugada syndrome (BS) is one of the most common channelopathies, with a worldwide prevalence of 0.05%. It is estimated that it accounts for 4% of all cardiac sudden deaths and most patients are diagnosed only after the arrhythmic event. It is possible to find the Type I pattern by evaluating the electrocardiogram (EKG), characterized by an elevation of 2mm in the concave ST segment morphology in right precordial leads, followed by a negative T wave and the Type II […]
