BACKGROUND:
Group A Streptococcus is one of the most morbid infections in modern obstetric practice. Pregnant women are known to have a 20-fold increased risk of invasive Group A Streptococcus with greatest risk in the first 4 days postpartum. The overwhelming majority of these infections will present with fever, uterine tenderness, or vaginal discharge. A much smaller subset may present to the Emergency Room after initial hospital discharge with much less obvious symptoms. In our case, persistent palpitations with unexplained tachycardia led to improper diagnosis in multiple Emergency Rooms.
