There were no dysrhythmias on cardiac monitor during observation. This discussion comes from this previous post: Hyperthermia and ST Elevation Discussion Brugada Type 1 ECG changes are associated with sudden cardiac death (SCD) and the occurrence of ventricular dysrhythmias. Circulation, 117, 1890–1893. [3]:

Could the dysrhythmias have been prevented? mEq of K pushed fast and circulated theoretically would raise serum K immediately by 1.0 Severe hypokalemia in the setting of STEMI or dysrhythmias is life-threatening and needs very rapid treatment. Since it takes some time (how long?) mEq/L, and 10 mEq would increase it by 3.3

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.

Patient course The patient was started on beta blockers and schedule for an electrophysiologic study. Because the AP lies outside of the AV node — the time to circulate around the reentry pathway and conduct back to the atria ( retrograde ) is longer than when the entire reentry circuit is contained within the AV node. Try adenosine.
