Key findings

  • Wide, regular, fast
  • Structural heart disease history
  • AV dissociation when visible is diagnostic

Learning points

  • A wide-complex tachycardia in a patient with prior infarction is VT until proven otherwise.
  • Hemodynamic stability never excludes VT; treat the rhythm, not the blood pressure alone.
