  3. Types: Narrow Complex Tachycardia (key question is 'regular or irregular')
    1. Sinus Tachycardia (regular)
    2. Irregular Supraventricular Tachycardia (may also present as wide complex if aberrancy)
      1. Atrial Fibrillation
    3. Regular Supraventricular Tachycardia
      1. Atrial Flutter
      2. Atrioventricular Nodal Reentry (AVNRT): 60% of SVT cases
      3. Atrioventricular Reciprocating Tachycardia (AVRT): 30% of SVT cases
      4. Atrial Tachycardia (AT): 10% of SVT cases
  4. Symptoms
    1. Chest pressure
    2. Dyspnea
    3. Fatigue
    4. Light headed
    5. Palpitations
  5. Signs
    1. Sinus Tachycardia
      1. P Waves present and normal
      2. Variable R-R with constant PR interval
      3. Rate lower than PSVT
        1. Infants < 220
        2. Children < 180
        3. Adults < 160
    2. Supraventricular Tachycardia
      1. P Waves absent or abnormal
      2. Abrupt rate change
      3. Rate higher than Sinus Tachycardia
        1. Infants > 220
        2. Children > 180
        3. Adults > 160
  6. Management: Stable Patients
    1. New emphasis on use of one Antiarrhythmic
      1. Contrast to prior Antiarrhythmic soups
      2. Pro-arrhythmic effects increase with poly-drugs
    2. Supraventricular Tachycardia Management in the Adult
    3. Supraventricular Tachycardia Management in the Child
  7. Management: Unstable Patients
