Arrhythmia Formation

  • Sinus node: brady/tachy
  • Atrial cells: supraventricular
  • AV junction: supraventricular
  • Ventricular cells

Supraventricular Arrhythmia

  • Atrial cells can:
    • Fire from a focus
    • A looping re-entrant circuit
    • Atrial Flutter

Atrial Fibrillation

  • Atrial Cell Problems

Ventricular Cell Problems

  • Premature Ventricular Contractions (PVCs)
  • Ventricular Fibrillation
  • Ventricular Tachycardia
