A 21-year-old woman is brought to the emergency department 25 minutes after she experienced dizziness and a “fluttering” sensation in her chest. ECG monitoring by first responders showed a polymorphic ventricular tachycardia that spontaneously reverted to a sinus rhythm. The entire episode lasted ~10 minutes. She has had two similar episodes over the last three days. These were less severe, lasted for only one to two minutes each, and then subsided spontaneously. She is two weeks postpartum. She delivered a healthy baby boy at 41 weeks of gestation, via an uncomplicated vaginal delivery. The antenatal period was without complications. Her medical, surgical, and family histories are unremarkable. She is not on any medications. She does not smoke and has not consumed alcohol since the start of her pregnancy. Prior to this, she used to consume an average of one to two standard drinks per week. She denies recreational drug use.
