Lead aVR on EKG
Lead aVR can provide some unique insight into 5 different conditions:

 - Acute MI
 - Pericarditis
 - Tricyclic antidepressant (TCA) and TCA-like overdose
 - AVRT in narrow complex tachycardias
 - Differentiating VT from SVT with aberrancy in wide complex tachycardias by using the Vereckei criteria (possibly better than Brugada criteria)
