Tip 82b: SVT 2

Presentation varies from antenatal hydrops and tachycardia, to neonatal heart failure within the first 12-24 hours, to being asymptomatic.

The termination of SVT is usually easily achieved by vagal manoeuvres (e.g. facial immersion in ice-cold water) or intravenous adenosine. Rarely, DC shock is needed, especially if there is evidence of cardiovascular compromise.
