Here is a recording of normal heart sounds in an infant. The normal heart rate at this age is 120 - 160 beats per minute. At times, healthy babies may have resting heart rates as low as 90s or 100, but further evaluation of those few is prudent to rule out the possibility of pathology.

Click on marked areas of the chest to hear the actual heart sounds with ascultation. (Use a headset to hear the sounds most clearly).
