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'!
The first sound of the heartbeat is the lup. It is produced when the bicuspid and tricuspid valves open to let the blood from the auricles enter the ventricles.
about 3 months
The heartbeat is one cycle of pumping in the heart, from the first electrical impulse in the "pacemaker" node to the final contraction of the left ventricle.

The closing of the atrioventricular valves provides the "LUB" part of a heartbeat, followed by the "DUB" of the semilunar valves (aortic and pulmonary valves).
A heartbeat has two parts the first part in the flow of the blood into the heart. The second part is the flow of the blood out of the heart. That is why heart beat is a bub-bub sound.
