Heart auscultation remains as an important clinical tool in heart disease diagnostics. A prototype was developed, using an existing database of clinical and cardiac sounds of pregnant women [1]. The context for virtual learning is cardiac disease during pregnancy (Partum and Post Partum situations).

Methods: To investigate the frequency and the targets of AABs in preeclamptic women (31 cases) and healthy pregnant normotensive women (29 cases) in Brazil, antibodies from serum samples were detected by a bioassay using spontaneously beating neonatal rat cardiomyocytes in culture. In the cardiomyocytes, the agonistic AABs induce a positive or negative chronotropic response, mimicking the corresponding receptor agonists.
