It should be kept in mind that on occasions, beta-one agonist can result in increased ventricular ectopy e.g., in severe myocardial ischemia (by increasing myocardial demand), or sometimes with congenital long-QT syndrome. Smith, this can be accomplished by either using beta-one agonists or temporary transvenous pacing.

At cath, he immediately had incessant Torsades de Pointes requiring defibrillation 7 times and requiring placement of a transvenous pacer for overdrive pacing at a rate of 80. If there is polymorphic VT with a long QT on the baseline ECG, then generally we call that Torsades, but Non-Torsades Polymorphic VT can result from ischemia alone.

It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation. In terms of ischemia, there is both a signal of subendocardial ischemia (STD max in V5-V6 with reciprocal STE in aVR) AND a signal of transmural infarction of the inferior wall with Q wave and STE in lead III with reciprocal STD in I and aVL.

The limb lead abnormalities appear to be part of the Brugada pattern, as described in this article: Inferior and Lateral Electrocardiographic RepolarizationAbnormalities in Brugada Syndrome Discussion Brugada Type 1 ECG changes are associated with sudden cardiac death (SCD) and the occurrence of ventricular dysrhythmias.
