When does a baby have a heartbeat? A baby's heartbeat can be detected by transvaginal ultrasound as early as 3 to 4 weeks after conception, or 5 to 6 weeks after the first day of the last menstrual period. This early embryonic heartbeat is fast, often about 160-180 beats per minutes, twice as fast as us adults'!
A bird's heartbeat depends on the bird in question. A hummingbird for example can have a heartbeat of about 180 beats per minute.
