A 29-year-old woman has a known history of palpitations from a diagnosis of supraventricular tachycardia that usually terminates when she performs a Valsalva maneuver. Today, she presents to the emergency department following a sudden onset of palpitations that persisted despite performing Valsalva several times. The palpitations are different now, and her heart rate is irregular. A 12-lead ECG is obtained.
