Normal sinus node recovery times (CSNRT) were established for adolescents aged 12-17 years. The upper limit of normal CSNRT in adolescents is approximately 445 msec, aiding in diagnosing sinus node dysfunction.

Area of Science:

Cardiology
Electrophysiology
Pediatric Medicine

Background:

Sinus node recovery time (CSNRT) assesses sinus node function in children and adults.
Established normal CSNRT values exist for young children and adults, but not for adolescents.
Sinus node dysfunction is a known complication after congenital heart disease repair.

Purpose of the Study:

To determine normal corrected sinus node recovery time (CSNRT) values for adolescent patients.
To establish reference ranges for CSNRT in individuals aged 12-17 years.

Main Methods:

CSNRT was measured in 29 adolescent patients (ages 12-17) undergoing electrophysiology testing.
Method involved rapid atrial pacing with decreasing pacing cycle lengths.
CSNRT calculated by subtracting resting sinus cycle length from maximal sinus node recovery time.

Main Results:

The mean CSNRT in adolescents was 323 ± 61 msec (range 186-422 msec).
A significant positive correlation was observed between CSNRT and patient age.
The upper limit of normal CSNRT for adolescents was determined to be approximately 445 msec (mean + 2 SD).

Conclusions:

Normal CSNRT values for adolescents fall between those of children and adults.
An approximate upper limit of normal CSNRT of 445 msec is proposed for adolescents.
This finding is clinically relevant for managing adolescents with congenital heart disease and potential sinus node dysfunction.
