DATA HIGHLIGHT : Age Differences in Heart Rate and Electrocardiogram Time Intervals

Center researchers characterizing inbred strains of mice for aging phenotypes at 6, 12 and 18 months of age have revealed a genetic influence on electrocardiogram (ECG) time intervals and heart rate in aging mice.

Data from these studies are presented below and have been deposited in the Mouse Phenome Database [ Datasets ]

Heart Rate Data

Examples of age differences in heart rates for C57L/J (C57L) females and BALB/cByJ (BALB) males (A) and in electrocardiogram time intervals: P-R intervals in 129S1 females (B) and QRS intervals in C57BR/cdJ (C57BR) males (C). Graphs show means +/- SD.
