Educational Pearls

• EKG changes that can be seen in DKA include ST elevation and peaked T-waves secondary to derangements in K levels.
• In DKA, serum K is high, but total body K is low, which can cause said EKG abnormalities.
• Many things cause ST elevation besides MI, so think beyond STEMI.
• When someone in in DKA, think about the "Three I's" for underlying cause: (not taking) insulin, ischemia, infection.
