ECG features of ventricular tachycardia

ECG features of ventricular tachycardia
  • QRS width >120 milliseconds
  • Shift in QRS axis, particularly to a "northwest" axis (between –90 and –180 degrees)
  • AV dissociation (including the presence of fusion complexes and/or capture beats)
  • Negative concordance in leads V1 to V6
  • RS >100 milliseconds in any of leads V1 to V6
  • Morphology:
  • VT with RBBB-like morphology in V1: R/S <1 in V6
  • VT with LBBB-like morphology in V1: Any Q wave in V6
ECG: electrocardiogram; AV: atrioventricular; VT: ventricular tachycardia; RBBB: right bundle branch block; LBBB: left bundle branch block.
