The World Health Organization (WHO) declared Sars-CoV infection and COVID-19 as a pandemic and global emergency. In addition to viral pneumonia and the severe acute respiratory syndrome (Sars), the heart is affected in some patients due to the detection of biomarkers and reported cases of myocarditis and pericarditis. Therefore, the knowledge of electrocardiogram presentation of these actual infections can guide the choice for the best treatment and can help to reduce misdiagnosis, mainly the acute myocardial infarction, which is the main differential diagnosis.
Bidirectional ventricular tachycardia (BDVT) is defined by beat-to-beat alternation of the QRS axis on the electrocardiogram. Its diagnosis is uncommon, and the most characteristic etiology is digitalis intoxication (DI). We report the case of a patient with heart failure of valve origin admitted for sepsis that progressed to BDVT and death, associated with DI.
A Síndrome de Brugada é uma doença cardíaca autossômica dominante causada por disfunções nos canais iônicos, cujos portadores apresentam padrão eletrocardiográfico clássico e predisposição a arritmias ventriculares malignas. As alterações do eletrocardiograma podem ser dinâmicas, espontâneas ou induzidas por drogas bloqueadoras dos canais de sódio (ajmalina, procainamida, etc.). No entanto, os achados eletrocardiográficos que diagnosticam Síndrome de Brugada podem ocorrer mesmo na ausência de disfunção congênita dos canais iônicos, caracterizando “fenocópia de Brugada”, portanto a exclusão de causas secundárias é fundamental para o correto diagnóstico da canalopatia.
Objetivo: Identificar o perfil dos pacientes que implantaram marcapasso e as suas complicações em um centro terciário de cardiologia do estado de Santa Catarina. Métodos: Estudo unicêntrico, observacional e prospectivo com 81 pacientes submetidos a implante de marcapasso pelo Serviço de Cirurgia Cardiovascular. Resultados: Marcapasso provisório foi necessário em 42 casos (51,8%) e o tempo médio de permanência do marcapasso provisório foi de 2,2 dias. Óbito ocorreu em 3 pacientes (3,7%), entretanto apenas 1 caso (1,2%) foi associado ao implante.Conclusão: As características clínicas e as indicações do implante da população do estudo foram semelhantes às encontradas na literatura, entretanto o número de complicações mostrou-se elevado e o tempo de permanência do marcapasso provisório está além do recomendado
Objective: To identify the profile of patients who implanted pacemakers and their complications in a tertiary cardiology center in the state of Santa Catarina. Methods: Unicentric, observational and prospective study with 81 patients submitted to pacemaker implantation by the Cardiovascular Surgery Service. Results: Provisional pacemaker was necessary in 42 cases (51.8%) and the average time of temporary pacemaker insertion was 2.2 days. Death occurred in 3 patients (3.7%), however only 1 case (1.2%) was associated with the implant. Conclusion: The clinical characteristics and indications of the implant in the study population were similar to those found in the literature, however the number of complications was high and the length of stay of the provisional pacemaker is beyond that recommended.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
