Dr. Smith's ECG Blog

DISCUSSION: The 12-lead EKG EMS initially obtained for this patient showed severe ischemia, with profound "infero-lateral" ST depression and reciprocal ST elevation in lead aVR. The ECG cannot diagnose the etiology of ischemia; it only the presence of ischemia, from whatever etiology.

STEMI with Life-Threatening Hypokalemia and Incessant Torsades de Pointes

Dr. Smith's ECG Blog

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. Could the dysrhythmias have been prevented? Severe hypokalemia in the setting of STEMI or dysrhythmias is life-threatening and needs very rapid treatment.

Young Man with a Heart Rate of 257. What is it and how to manage?

Dr. Smith's ECG Blog

If the rhythm converts and then reverts to tachycardia with either adenosine or electricity, Neither one of those modalities should be attempted until some longer acting pharmacological solution is given. WPW does not always have delta waves on the baseline ECG. This is called "Concealed conduction".
