Ventricular Tachycardia Management in the Child

Aka: Ventricular Tachycardia Management in the Child
  1. See Also
    1. Ventricular Tachycardia Management in the Adult
    2. Unstable Tachycardia
  2. Indications: Wide Complex Tachycardia in Children
    1. Tachycardia AND
    2. Wide QRS Complex (duration > 0.08 sec)
      1. Note adult wide complex is defined as (at least 0.12 sec)
  3. Approach
    1. No pulse
      1. Treat as Pulseless Ventricular Tachycardia
    2. Unstable (shock or ALOC)
      1. Treat as Unstable Ventricular Tachycardia
      2. Administer Synchronized Cardioversion
    3. Stable
      1. Treat per protocol below
  4. Protocol: Stable Wide Complex Tachycardia (presumed Ventricular Tachycardia) Management
    1. Electrical Cardioversion if unstable or refractory to below measures
      1. Sedation and analgesia if no delay
      2. Synchronized Cardioversion Dose
        1. First: 0.5-1.0 Joules/kg
        2. Next: 2.0 Joules/kg
    2. Step 1: Adenosine
      1. AVOID if polymorphic or irregular Wide Complex Tachycardia (can degenerate to VF)
      2. Dose
        1. First: 0.1 mg/kg (max 6 mg) rapid IV push
        2. Next: 0.2 mg/kg (max 12 mg) rapid IV push
      3. Effect
        1. SVT: converts or at least slows rhythm for interpretation
        2. VT: no effect (unless irregular, in which case could degenerate into VF)
    3. Step 2: Choose one Antiarrhythmic (do not use both)
      1. Consultation with pediatric cardiology recommended
      2. Amiodarone 5 mg/kg (max 150 mg) IV over 20 to 60 minutes OR
      3. Procainamide 15 mg/kg IV over 30 to 60 minutes

Tachycardia, Ventricular (C0042514)

Definition (NCI) A disorder characterized by an electrocardiographic finding of three or more consecutive complexes of ventricular origin with a rate greater than a certain threshold (100 or 120 beats per minute are commonly used). The QRS complexes are wide and have an abnormal morphology. (CDISC)
Definition (NCI_CTCAE) A disorder characterized by a dysrhythmia with a heart rate greater than 100 beats per minute that originates distal to the bundle of His.
Definition (NCI_FDA) An abnormally rapid ventricular rhythm with aberrant ventricular excitation, usually in excess of 150 beats per minute.
Definition (MSH) An abnormally rapid ventricular rhythm usually in excess of 150 beats per minute. It is generated within the ventricle below the BUNDLE OF HIS, either as autonomic impulse formation or reentrant impulse conduction. Depending on the etiology, onset of ventricular tachycardia can be paroxysmal (sudden) or nonparoxysmal, its wide QRS complexes can be uniform or polymorphic, and the ventricular beating may be independent of the atrial beating (AV dissociation).
