Postnatal changes in heart rate, duration or interval, amplitude, mean electrical axis of QRS complex and ST-segment of the standard limb-lead ECG in voles and Mongolian gerbils were studied. 1) The heart rate in both animal species increased until the 21st day of the postnatal stage and thereafter decreased gradually. 2) The shortest PR and QT intervals were observed at the 14th or 21st day in both species. The QRS durations of voles were also shortened toward the 7th day and were then prolonged, whereas in Mongolian gerbils they were almost completely stable until the 60th day. There were significant positive correlations between the RR intervals and PR or QT intervals in both species. 3) The amplitude of the P and R waves was maximum at the 14th (vole) or 21st (Mongolian gerbil) day. The amplitude of the T wave increased from the 7th to the 21st day and decreased thereafter, while the S wave was maximum at the 14th (vole) and 21st days (Mongolian gerbil). 4) The mean electrical axis of the QRS complex was seem predominantly in the right and caudal directions and shifted to the left and caudal directions with maturation. 5) The ST-segment was recognized in the earliest stage but became obscure as age advanced. In some voles the ST-junction disappeared in mature stages, whereas in all Mongolian gerbils the ST-junction was present.
