Summary

New electrophysiological parameters for sinus node dysfunction (SAND) in children are established. These age- and gender-specific values improve the accurate diagnosis of sinus node recovery time and sinoatrial conduction time.

Area of Science:

  • Pediatric Cardiology
  • Electrophysiology
  • Cardiac Electrophysiology

Background:

  • Sinus node dysfunction (SAND) can be congenital or acquired.
  • Electrophysiological (EP) parameters, including corrected sinus node recovery time (CSNRT) and sinoatrial conduction time (SACT), are used to evaluate sinus node function.
  • Current diagnostic norms may not adequately account for age and gender variations in pediatric populations.

Purpose of the Study:

  • To determine age- and gender-specific reference values for CSNRT and SACT in pediatric patients without structural congenital heart disease.
  • To establish new normative data for evaluating sinus node function in children.

Main Methods:

  • Retrospective analysis of EP study data from 152 pediatric patients undergoing evaluation for supraventricular tachycardia.

  • Data collected between 1997 and 2002.
  • Patients received standard anesthesia (midazolam, propofol, isoflurane) known not to affect EP parameters.

    • Main Results:

    • A significant age transition for CSNRT was observed at 14 years.
    • Upper limits of normal CSNRT (445 msec) and SACT (120 msec) differed from current norms in younger children.
    • Males exhibited significantly longer CSNRT and atrial refractory periods compared to age-matched females.

    Conclusions:

    • Established age- and gender-specific EP parameter values provide a more precise method for recognizing SAND in pediatric patients.
    • Revised normative data are crucial for accurate diagnosis and management of sinus node dysfunction in children.
