Quick Q&A

Q: What is heartbeat legislation?

A: Heartbeat legislation is a colloquial term for legislative bills which would protect the unborn from abortion after the unborn human has detectable heartbeat. To date, all heartbeat legislation has been introduced and fought at the state level.

Q: Would these bills put women in jail?

A: No, all heartbeat bills which have been proposed penalize the abortionist, not the woman. The proposed penalties vary depending on whether the doctor failed to check for a heartbeat, or found a heartbeat and still performed the abortion.

The proposed penalties also vary by state: some suggested the revocation of a medical licenses- while others gave fines for violations. Some heartbeat bills even included provisions so that women upon whom an abortion was performed could, in some circumstances, file a civil action suit for the wrongful death of her child.


Biology and Development

-The cardiovascular system is the first major system to function in a human embryo.

– The heart and vascular system appear in the middle of the third week; the heart begins to beat about 23/24 days after fertilization.

– The heart starts to form into atriums and ventricles during the middle of the 4th week, and these are completed in the eighth week after fertilization.

– When the heart is new (during the third week after fertilization) the circulation in the heart is ebb-and-flow.

– By the fourth week, the heart has coordinated contractions and blood flow in and out of the heart is one-directional.


Fertilization: The moment at which the sperm and egg meet (aka: conception). This can occur between 5 minutes to 5 days after intercourse. All 46 chromosomes are present at this moment—23 from mom and 23 from dad. The child’s gender, eye color, hair color and many other things are already decided. All that is needed is time for the child to grow.

Zygote: A highly specialized totipotent cell which is formed when the male sperm unites with a female gamete and which marks the beginning of human development.

Embryo: The developing human during its early stages of development.The embryonic period extends to the end of the eighth week (56 days), by which time the beginnings of all major structures are present.

Fetus (Medical): Unborn offspring; after the embryonic period (8 weeks) and until birth, the developing human is called a fetus. During the fetal period (ninth week to birth), differentiation and growth of the tissues and organs formed during the embryonic period occur.

Fetus (Legislative): In the text of heartbeat legislation, the term “fetus” is commonly defined as “the human offspring developing during pregnancy from the moment of conception and includes the embryonic stage of development.” [emphasis added.]


Atrium: A chamber of the heart that receives blood from the veins and forces it into a ventricle or ventricles

Ventricle: A chamber of the heart which receives blood from a corresponding atrium and from which blood is forced into the arteries

Vein: Any of the tubular branching vessels that carry blood toward the heart

Artery: Any of the tubular branching muscular- and elastic-walled vessels that carry blood away from the heart and through the body

Fetal Heartbeat: Cardiac activity, the steady and repetitive rhythmic contraction of the fetal heart within the gestational sac.
