Presentation Transcript

  1. Ventricular Tachycardia in Pediatrics

  2. Definition: tachycardia of at least 3 successive ventricular beats.

  3. Terminology • Non-sustained: rhythm lasts <30 seconds and terminates spontaneously • Sustained: lasts >30 seconds and usually requires therapeutic intervention

  4. Ventricular Tachycardia • Most commonly seen in kids with abnormal hearts. • Many asymptomatic • Symptoms you can see: pallor, fatigue, and chest palpitations. • In infants, VT often manifests as feeding intolerance.

  5. Ventricular Tachycardia • Better prognosis in kids that have a healthy heart. • Causative factors (outside of an underlying cardiac disease): drugs, caffeine, decongestants, and electrolyte imbalances.

  6. ECG • Wide QRS complex (>120 msec) • Tachycardia (usually has a regular rhythm) • P-waves may or may not be recognizable, depending on ventricular rate. • T-waves typically opposite in polarization to the QRS • QRS complex may vary in appearance if ectopic input is multifocal.
