Idk y’all…I’m gonna have to go with the American College of Obstetrics & Gynecology (left) and the manufacturer of Doppler ultrasounds (right) on this one & not just…some guy It’s true: Doppler artificially produces the pulsing sound often falsely interpreted as a “heartbeat.”

Screenshot of a resource from ACOG that states, “What pregnant people may hear is the ultrasound machine translating electronic impulses that signify fetal cardiac activity into the sound that we recognize as a heartbeat.”
A screenshot of a Doppler service manual that says, “It is important to remember that the sound you hear is an artificial sound, the frequency (pitch) of which is proportional to the velocity of the moving target. It is not the real sound made by blood rushing through an artery or vein, or movement of the fetal heart.”

Georgia Democrat Stacey Abrams: "There is no such thing as a heartbeat at six weeks. It is a manufactured sound designed to convince people that men have the right to take control of a woman's body." REMINDER: Abrams supports NO LIMITS on abortion.

By "artificially," I don't mean "made up." Ultrasound interprets calcium-induced electrical activity from cardiac cells (NOT a true heart yet -- primitive cardiac tissue) as sound. Cardiac cells contract alone in a petri dish. Seeing & hearing does not a 'heartbeat' make.

There's no "heartbeat" at 6 wks LMP (28 days PF) b/c there's no true "heart" & no true "beat." I understand that sounds complicated--it is. The anti-abortion movement has taken advantage of that complexity to push the emotionally-charged myth that Abrams is calling out. See E28:

Dammit, ACOG stands for the *American College of Obstetricians and Gynecologists* but you get the idea
