AbstractAccurate prehospital diagnosis and early initiation of emergency medical treatment for pediatric patients found to have supraventricular tachycardia is a reasonable task to accomplish and one that does not have to be anxiety-provoking. The most important point to remember is that the standard approach to resuscitation and stabilization for pediatric patients with narrow complex tachycardias (and those with aberrant or wide complexes identifiable as WPW) applies to all variations of SVT; thus, it is not necessary to precisely diagnose the variant prior to initiation of treatment, except for WPW, in which adenosine administration is contraindicated. Once the dysrhythmia is identified as SVT, the patient must rapidly be categorized as stable or unstable, which will then lead the EMS provider down the correct branch of the treatment algorithm. Every attempt should be made to perform a 12-lead ECG pre- and post-resuscitation, as well at to administer sedation prior to emergent synchronized cardioversion. Dosages of medications need not be memorized, provided that a readily available guide, such as a Broselow tape or regional tertiary care center laminated resuscitation card, is at hand. Finally, while termination of pediatric SVT, whether spontaneous or by EMS intervention, will also likely terminate the EMS provider's own palpitations, it is essential that these patients be seen in an emergency department immediately in order to accurately diagnose their medical condition and provide the patient and family with an appropriate disposition based on the events surrounding the incident.
