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 are the 3 components of the ECG trace?
The EKG or ECG components are the P wave (contraction of the atria), the QRS complex (the contraction of the ventricles) and the T wave (repolarization of the ventricles).
What electrical event in the heart does the QRS complex represent?
Depolarization of ventricles
What carries electrical impulses across the heart and causes the ventricles contract?
SA node.
What electrical event is responsible for making sure the ventricles contract after the atria have contracted?
Purkinje 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.
When does your heart get 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.
What are AV nodes?
AV node is biologically an inhibitor of the conduction across the atrium to ventricles. The conduction of impulse is delayed across the AV node. This buys time for the atria to contract, to be fallowed by ventricles.
What structure of the conduction system helps to cause the constriction of the ventricles and extend from the atrioventricular node?
The conduction speed slows when it reaches the bundle of His, and then speeds up as it travels along the Purkinje fibres to the base of the ventricles.
What are AV nodes biologically?
AV node is biologically an inhibitor of the conduction across the atrium to ventricles. The conduction of impulse is delayed across the AV node. This buys time for the atria to contract, to be fallowed by ventricles.
What part of the conduction system prevents the ventricles from beating as fast as the atria?
heart

Can someone help you decipher your EKG report It says sinus tachycardia borderline AV conduction delay and probable left atrial abnormality.?
sinus tachycardia = rapid heartbeat borderline av conduction delay = a slight delay in the conduction of electrical impulse from the atria, at the top of the heart, to the ventricles, at the base of the heart. The ventricles are the chambers that do the pumping of blood to the lungs and to the body. The atria are the two "collecting" chambers for the blood returning to the heart from the lungs and from the body. The electrical impulse of a heartbeat starts in the right atrium, travels across to the left atrium and down to the top of the ventricles. This causes the atria to contract and push blood through heart valves into the chambers of the heart called Ventricles. The contraction then has a slight pause as the impulse "stimulates" the atrioventricular node to pass the impulse down to the base of the right and left ventricles. When the impulse passes the AV node, the ventricles contract and push the blood out to the lungs to be oxygenated and to the body. A slight delay in the conduction of the impulse is normal but it is only a fraction of a second. Any delay in the conduction which is longer than the "normal" fraction of a second is considered an abnormal av conduction delay. Probable Left Atrial abnormality = some kind of abnormal size, shape, structure, or electrical conduction in the chamber at the top of the left side of the heart. Remember that the atria are chambers for collecting blood returning to the heart. The left atrium is the chamber for collecting blood which is returning from the lungs. This is freshly oxygenated blood. The blood travels from the lungs to the left atrium. When the atria contract, the blood is pushed from the left atrium into the left ventricle. When the ventricles contract, the blood is then pumped from the left ventricle out into the aorta (the largest artery in your body) and then on to the furthest reaches of your body.
What is the group of cells that adjust the speed heart beat?
The bundle of His is a collection of heart muscle cells specialized for electrical conduction that transmits the http://wiki.answers.com/index.php/Action_potentialfrom the http://wiki.answers.com/index.php/AV_node(located between the atria and the ventricles) to the point of the apex of the fascicular branches. The fascicular branches then lead to the http://wiki.answers.com/index.php/Purkinje_fiberswhich innervate the ventricles, causing the http://wiki.answers.com/index.php/Cardiac_muscleof the ventricles to contract at a paced interval.I copy pasted this here, because I thought it was the bundle of His, and this does talk about how they do to electrical conduction. Is this what you are looking for?
What component of the conduction system is located between the ventricles?
there is the junctional node, the bundle of his and the left and right bundle branches
Normal electrical recovery of the ventricles is represented on the ekg by the?
T waves
