Results Results and discussion
Propofol significantly suppressed intrinsic cardiac HV conduction, but did not affect the SNRT, SACT or the AH interval. As HV blocks, which occur below the His bundle, are often life-threatening, the HV conduction delay may be a cause of severe AV blocks induced by propofol. Propofol directly suppressed parasympathetic nerve activity, and sympathetic nerve activity was also suppressed.

Baseline Characteristics Twenty-three patients (age: 6-15 years; males: 16, females: 7) who were scheduled to undergo radiofrequency catheter ablation (RFCA) were prospectively enrolled in this study.
All of the patients had physical statuses of I or II according to the American Society of Anesthesiologists classification and apart from their cardiac arrhythmias were otherwise healthy
Participant flow written informed consent from the parents of the patients.
The administration of all anti-arrhythmia drugs was stopped 2 days before the RFCA. The patients did not receive any premedication.
Adverse events none
Outcome measures sinus node recovery time
sinoatrial conduction time
atrial-His intervals
