- The differential for wide complex tachycardia includes ventricular tachycardia, SVT with aberrancy, and SVT with a bypass track (WPW).
- Characteristics of V tach include capture/fusion beats, AV dissociation, Northwest axis, precordial concordance.
- Akhtar Criteria: In patients with a history of MI, new onset wide complex tachycardia is >95% ventricular tachycardia
- Remember Idiopathic V-Tach (often from the right ventricular outflow tract) and Arrhythmogenic right ventricular dysplasia as causes of V-tach in a young person
