where does the heart beat begin?

Question

the question is where not when... where in your body does the heart beat begin?

Ill ask the question differently .......Does the Heart beat begin in the right ventricle?

Answer 1

if u mean where the starting point of the heart tissue depolarisation-- it is initiated at the pacemaker sinoatrial node located near the opening of vena cava (in the right atrium wall). once the tissue is depolarised, it will begin contraction ( because of the velocity of the electrical impulses the two atria contract at relatively the same time). so to make thing short.. heart beat begins with atrial contraction and followed by ventricular contraction

Answer 2

The human embryonic heart begins beating approximately 21 days after conception, or five weeks after the last normal menstrual period (LMP), which is the date normally used to date pregnancy. The human heart begins beating at a rate near the mother’s, about 75-80 beats per minute (bpm). The embryonic heart rate (EHR) then accelerates linearly for the first month of beating, peaking at 165-185 bpm during the early 7th week, (early 9th week after the LMP). This acceleration is approximately 3.3 bpm per day, or about 10 bpm every three days, an increase of 100 bpm in the first month.

Answer 3

Hmm... i'm not really sure what are you asking exactly. Since you asked where, so I'll try explaining the initiation of heart beat...

Initiation of heart beat begins at the sinal-atrial (SA) node, which is also known as the pacemaker of the heart.
The SA node is found on the wall of the right atrium of the heart.

The electric impulse generated here subsequently spreads across the heart (first to the AV node, then Bundle of His, then the Purkynje fibres) in the coordination of heartbeat.

Answer 4

Your heart is located between your lungs in the middle of your chest, behind and slightly to the left of your breastbone (sternum). A double-layered membrane called the pericardium surrounds your heart like a sac. The outer layer of the pericardium surrounds the roots of your heart's major blood vessels and is attached by ligaments to your spinal column, diaphragm, and other parts of your body. The inner layer of the pericardium is attached to the heart muscle. A coating of fluid separates the two layers of membrane, letting the heart move as it beats, yet still be attached to your body

Answer 5

I personally feel tht heart beat begin when the person is born but it beats in the left side of the CHEAST.

Answer 6

Five signs of life in the womb:

1. Heartbeat

Modern technology can detect a baby's heartbeat eighteen days after conception.


That is only four days after most women miss a period and begin to suspect they are pregnant.


Most abortions are not performed until the eighth week (56 days) of a pregnancy, or a little later.

2. Brain waves

Six weeks after conception signals from the fetal brain can be detected.


Dream patterns have been discovered around the eighth or ninth week.


Perhaps more advanced technology will someday show us heartbeats and brain waves at even earlier stages in the unborn child's life.
3. Independent movement

At about the sixth week, the baby in the womb can move spontaneously: Kicking, swimming, jumping and stretching.


This is long before the mother will feel any sensations of movement.
4. Senses

A baby in the womb is capable of responding to touch and sound by about the eighth or tenth week.


A child at that age will move away from painful stimuli, the most painful of which would be the abortionist's instrument.
5. Breathing

By about the fourteenth week, a baby's lungs are functioning and he or she will practice breathing.


Vocal cords are formed by the thirteenth week, and were it not for a lack of air, the baby could be heard to cry!


At the moment of fertilization of a woman's ovum (egg) by a man's sperm, a new individual is created. This new individual possesses half of his or her chromosomes from the mother and half from the father. A new individual is formed, one with unique characteristics which have never been nor will ever be possessed by any other individual.
The "spark of life" is passed from the present generation to the next generation at conception.
Those who believe in God believe that the Spirit of God (God's breath first breathed into Adam) is passed to the new individual at conception. God-given life and an eternal soul are given to the new person.
All definitions of life which begin at a date later than conception are artificial and arbitrary, and often are proposed only to support the practice of abortion.

An argument is made that the unborn baby must depend on his or her mother for support. Is this the definition of life? Every unborn baby has the potential to be born and to grow, eventually becoming a self-supporting, self-sustaining individual independent of his or her mother. Can a comatose patient be killed, based on the argument that he or she must depend upon doctors and nurses for support? Can an anesthetized patient be killed, based on the argument that he or she must depend upon the anesthesiologist for support? Can a severely retarded or handicapped child be killed, based on the argument that he or she must depend upon parents for support?

Consider the evidence for yourself, rather than relying upon pro-abortion advocates. The following sites may help you better understand when life begins.

Listen to an unborn baby's heartbeat:

See four-dimensional ultrasound images of unborn babies:

See intrauterine photographs of unborn babies:


Photos of the Pre-Born...

After you hear a baby's beating heart, see the photographs, and watch moving babies in their mothers' wombs, consider whether these beautiful creations are "choices" (merely clumps of cells), or whether they are babies, fully entitled to life and protection.

Answer 7

I think approximately 3 weeks after conception and brain waves at 6 weeks. How amazing!

Answer 8

right ventricle to right atrium then it gets circulated through the lungs then left ventricle to the left atrium then through the body, begin again

Answer 9

Around the 5th week after conception. I could be wrong. Educational guess :)
