Paroxysmal supraventricular tachycardia (SVT) is a common emergency department presentation. Vagal maneuvers are commonly tried to terminate SVT but are often unsuccessful in terminating the dysrhythmia. The use of adenosine, while often successful, is associated with a number of side effects and is often disliked by patients with recurrent episodes of SVT. ⋯ The patient received intranasal stimulation with a nasopharyngeal swab used for COVID-19 testing for 5-10 s. After less than 10 s, the patient converted to a sinus rhythm. She was successfully discharged from the ED after 1 h of observation and no recurrence of her SVT.

Allergic reactions to Crotalidae polyvalent immune Fab and Crotalidae immune F(ab')2 are uncommon but potentially life-threatening. It is unknown whether cross-reactivity reactions exist between these two antivenoms. We report a case of a patient who suffered anaphylaxis from Crotalidae polyvalent immune Fab but subsequently was safely administered Crotalidae immune F(ab')2 after a presumed Agkistrodon contortix (copperhead) envenomation. This single case supports the safety of Crotalidae immune F(ab')2 administration in patients with a history of anaphylaxis to Crotalidae polyvalent immune Fab treatment.

Après Moi, Le Deluge: The identification and management of flood syndrome in the emergency department.
Umbilical hernias develop in approximately 20% of patients with liver cirrhosis and ascites. Flood Syndrome is an eponym describing the spontaneous rupture of these umbilical hernias due to the elevated intrabdominal pressure associated with large-volume ascites. Though rare, Flood Syndrome is associated with several life-threatening sequela including infection, organ failure, and hypovolemic shock, leading to mortality or transplant in over 30% of patients. The following case is a single patient encounter describing an 80-year-old female with long-standing ascites who presented to the Emergency Department shortly after experiencing a spontaneous extravasation of fluid from her umbilical hernia.
