We report the case of a patient who developed spontaneously a ventricular fibrillation during atrial fibrillation, 8 min after a perfusion of isoproterenol was stopped. Two mechanisms could explain the ventricular arrhythmia: silent ischaemia and a long-short cycle sequence just before ventricular fibrillation.
COVID-19 has now claimed several thousands of lives and overwhelmed the healthcare systems of several countries. Patients with cardiovascular disease are at particular risk not just of the infection itself but of its cardiac complications. Compared to other hospitalized patients with COVID-19, those needing intensive care, are more likely to have preexisting cardiovascular diseases or risk factors. Cytokine storm with hyperinflammation correlates with the severity of the disease. It is associated with mortality and is a key factor in determining the clinical course of extrapulmonary multiple-organ failure, suggesting that the inflammatory storm is associated with damage in extrapulmonary tissues and organs. Advanced Cardiac and Pulmonary Support has been reported in selected a COVID population.
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.
