Pediatric Supraventricular Tachycardia

  • Etiology: rhythm disturbance leading to pump disturbance leading to insufficient cardiac output
  • Imaging: cardiomegaly and congestive heart failure
  • Treatment: digoxin

Radiology Cases of Supraventricular Tachycardia

CXR of pulmonary edema in paroxysmal atrial tachycardia
CXR AP shows mild cardiomegaly and bilateral perihilar interstitial infiltrates due to pulmonary vascular congestion.
CXR of tachyarrythmia cardiomyopathy
CXR AP shows increased pulmonary vascularity and mild cardiomegaly.
