What is a S3 gallop?

The third heart sound (S3), also known as the “ventricular gallop,” occurs just after S2 when the mitral valve opens, allowing passive filling of the left ventricle. The S3 sound is actually produced by the large amount of blood striking a very compliant left ventricle.

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’!
