We have also shown several cases in which atrial flutter hides true, active ischemia. Tachycardia and ST Elevation. Tachycardia to this degree can cause ST segment changes in several ways. Tachycardia to this degree can cause ST segment changes in several ways. Christmas Eve Special Gift!! Is this inferor STEMI?

Is there ischemia? ECG Diagnosis is either : 1) junctional rhythm with new LBBB, and possibly ischemia 2) accelerated idoventricular rhythm with possible ischemia, and possibly related to restoration of normal perfusion. The second explanation (AIVR), whether as a reperfusion dysrhythmia or not, seems most likely.

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. Even with tachycardia and a paced QRS duration of ~0.16 No wall motion abnormality. (J J Am Coll Cardiol.

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.

The ECG shows sinus tachycardia with RBBB and LAFB, without clear additional superimposed signs of ischemia. See these publications for more information Overall, management for cardiac contusion is mostly supportive unless surgical complications develop, involving appropriate treatment of dysrhythmias and hemodynamic instability.

We see a regular tachycardia with a narrow QRS complex and no evidence of OMI or subendocardial ischemia. The differential of a regular narrow QRS tachycardia is sinus tachycardia, SVT, and atrial flutter with regular conduction. Now the patient is in sinus tachycardia. Her initial EKG is below. Adenosine worked.

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 rhythm is atrial fibrillation. The QRS complex is within normal limits.
