mortality/aging
• 67% of mice die early with a median life span of 16 months

cardiovascular system
• irregular heart rhythm and sudden drops in heart rate
• increase in heart rate variability during both the light and dark cycles
• heart rate during the dark cycle is decreased but is not different during the light cycle
• mice show an increased rate of spontaneous ventricular arrhythmias including premature ventricular contractions and nonsustained ventricular tachycardia
• mice show an increased rate of spontaneous ventricular arrhythmias including premature ventricular contractions and nonsustained ventricular tachycardia
• mice are highly susceptible to inducible arrhythmias

homeostasis/metabolism
• mice are highly susceptible to inducible arrhythmias
• mice exhibit decreased temperature during the dark cycle but not the light cycle

behavior/neurological
N
• mice show no differences in activity during the light or dark cycle
