Presentation Transcript

    1. Differential Diagnosis of Wide Complex Tachycardias Necessary for appropriate treatment CCBs can be very bad in WPW Based on correlation studies Identify factors that favor one rhythm Possibilities: VT, SVT with aberrant conduction, Afib/Aflutter with aberrant conduction

    3. Factors Favoring VT Concordance across all V leads (+/-) ERAD axis deviation QRS > .14 sec AV dissociation Suggestive QRS morphology
