results demonstrated that neonatal hearts had a significantly shorter ( p less than .05 ) tic ( 29.5 +/- 1.7 min ) than adult hearts ( 43.0 +/- 2.9 min ) and exhibited more rapid lactate accumulation ( 2.5 +/- 0.5 to 22.1 +/- 3.0 , p less than .001 ) and an increase in g-6-p ( 0.07 +/- 0.03 to 0.34 +/- 0.07 , p less than .01 ) with a nonsignificant decline in myocardial glycogen ( 23.3 +/- 12.1 to 17.4 +/- 4.0 , p greater than .05 ) .
