Interventions

  • Temporary Atrial Pacing — OTHER
    Temporary atrial pacing is delivered using temporary epicardial atrial pacing wires placed during cardiac surgery. During the protocol-directed pacing period, participants receive atrial pacing at either 10 or 20 beats per minute above their intrinsic sinus heart rate, according to their randomly assigned sequence. Each pacing condition is maintained for approximately three hours. The comparison condition is intrinsic sinus rhythm without protocol-directed atrial pacing. The protocol-directed pacing period occurs during approximately the first 10 postoperative hours. Pacing may be temporarily interrupted, skipped, or discontinued at the discretion of the treating clinical team when clinically indicated.

Study Details

The goal of this study is to determine whether temporarily increasing a child's heart rate after heart surgery can improve blood flow and oxygen supply to the body's tissues. The study will compare temporary atrial pacing at 10 and 20 beats per minute above the child's natural heart rate with the child's natural heart rate without pacing. Participants will be randomly assigned to one of two schedules for these pacing approaches. Each pacing approach has previously been used as part of routine care after heart surgery. The study will test whether temporarily increasing the heart rate improves blood flow and oxygen supply during the first 10 hours after surgery.

Arms

  • Experimental: Group 1: No pacing, +20 bpm, +10 bpm
    Participants first undergo intrinsic sinus rhythm without protocol-directed atrial pacing, followed by temporary atrial pacing at 20 beats per minute above the intrinsic sinus rate and then 10 beats per minute above the intrinsic sinus rate. Each condition is maintained for approximately three hours.
  • Experimental: Group 2: +20 bpm, +10 bpm, no pacing
    Participants first undergo temporary atrial pacing at 20 beats per minute above the intrinsic sinus rate, followed by atrial pacing at 10 beats per minute above the intrinsic sinus rate and then intrinsic sinus rhythm without protocol-directed atrial pacing. Each condition is maintained for approximately three hours.

Primary Outcome Measure

Change in Mean Renal Near-Infrared Spectroscopy (NIRS) Across Three Pacing Conditions [ Time Frame: The time frame for the mean renal NIRS will be during the final 30 minutes of each of the approximately 3-hour pacing conditions. ]
