Period prevalences of arrhythmias. The period prevalences of all arrhythmias as well as of the individual types of arrhythmias preoperatively, continuously during the first 72 hours after cardiopulmonary bypass and prior to discharge in A) neonates and B) non-neonates. The p values shown pertain to the comparison of the overall prevalence arrhythmias during the respective period with the preceding Holter monitoring period. No p values are shown when the difference was non-significant.
