What are the electrical impulses in the heart that are relayed to the ventricles by what?

A junction box, also known as the AV node, is how electrical impulses in the heart are relayed to the ventricles. The ventricles help make the muscle contract and then pump the blood.

What carries electrical impulses across the heart and causes the ventricles contract?
SA node.
What is the precise amount of electrical pulses does the brain send the heart?
The brain does not send "electrical pulses" to the heart. Electrical impulses are actually generated within the heart itself (in the SA node), which travel through several intricate pathways from the atria down to the ventricles.
What is happening during a complete heart block?
Complete heart block is where the electrical impulses from the SA node of the heart cannot reach the ventricles along the normal pathway. Instead the atrial contract from the SA node singles and the ventricles contract from the ventricular cells
What electrical event in the heart does the QRS complex represent?
Depolarization of ventricles
What creates the electrical signal in your heart?
neural impulses from the brain
What carries electrical impulses across the heart and causes the ventricles contract?
SA node.
What is Wolff-Parkinson-White syndrome?
An abnormal, rapid heart rhythm, due to an extra pathway for the electrical impulses to travel from the atria to the ventricles.

Phil has heart block His electrical impulses are being blocked from reaching the ventricles An electrical device that causes ventricular contractions at a rate necessary to maintain circulation is b?
The electrical device is a pace maker.
Which is a very serious type of heart block in which no impulses are conducted to the ventricles?
third degree heart block
What is the medical term meaning interruption of the electrical impulses in the heart's conduction system?
Heart block is the term meaning interruption of electrical impulses in the heart's conduction system.
What is the pacemaker of the heart that begins the heartbeat?
The SA node begins the heartbeat and is sometimes referred to as the heart's pacemaker. The AV node are where the electrical impulses are delayed for 0.1 second before spreading to both ventricles and causing them to contract.
What electrical event in the heart does the QRS complex represent?
Depolarization of ventricles
What creates the electrical signal in your heart?
neural impulses from the brain
What is the name of the structure in the heart which distributes the electrical impulses to the ventricles?
Bundle of Hisatrioventicular bundle (bundle of his), right and left bundle bramches and the purkinge conducition fibers
When does the human heart rest?
The electrical impulse reaches all the muscle tissue in the ventricles, and the ventricles contract. This electrical conduction pattern occurs approx. every 0.8 seconds.
