A 34-year-old female with no reported medical history presents to urgent care after a syncopal episode. She describes standing up rapidly to answer the phone, followed by a sensation of lightheadedness and nausea with subsequent collapse.
On evaluation, her vital signs are normal, she appears well, and she is currently asymptomatic.
View the ECG taken and consider what your diagnosis and next steps would be.
