HPI
A 30-year-old woman presents with one hour of chest discomfort and palpitations. On arrival she is borderline but not frankly unstable. The 12-lead shows a fast rhythm that appears wide at first glance. Cardiology and then EP are consulted and label it VT. Multiple cardioversions and adenosine are given without effect. The patient decompensates, is intubated, and progresses to cardiac arrest with unsuccessful resuscitation.
