If the atrioventricular node could be surgically removed from the heart without disrupting signal transmission to the Purkinje fibers what would be the effect?

Atria and ventricles would contract at about the same time.

Can purkinje fibers self-excite?
Purkinje fibers refer to a unique cardiac end-organ. They are split in atria and ventricles walls and can undergo self-excitation.
What is The order of impulse conduction in the heart from beginning to end?
The impulse starts in the right atria in the sinus node, then travels through the intratrial fibers for atrial contraction, then travels down to the the av node where it is delayed, then travels down through the bundle branches to the purkinjee fibers to the ventricular myocardium for contraction.
What is the point in the purkinje system where the impulse is temporarily delayed?
the atrioventricular node :)
What is the the correct path for the transmission of an impulse in the intrinsic conduction system of the heart?
sinoatrial (SA) node, atrioventricular (AV) node, atrioventricular (AV) bundle, right and left bundle branches, Purkinje fibers
Are moderator band and Purkinje fibers branches of Atrioventricular bundles?
Yes, the Purkinje fibers branch from the atrioventricular node down through the interventricular septum and traven through the walls of the heart. A branch leaves the wall and travels through/with the moderator band.
Name the elements of the intrinsic conduction system in order?
1. Sinoatrial node2. Atrioventricular node3. Atrioventricular bundle4. Right and left bundle branches5. Purkinje fibersThis answer may be acceptable for high school, but in university you'll have to go further as such:1. Sinoatrial node2. Posterior, anterior, lateral internodal pathway + Bachmann's bundle3. Penetrating Atrioventircular node4. Distal Atrioventricular node5. Left and right bundle branches of Purkinje fibers (or: left and right Bundles of His)6. Purkinje fibers
What is the correct path for the transmission of an impulse in the instrinsic condition system of the heart?
sinoatrial (SA) node, atrioventricular (AV) node, atrioventricular (AV) bundle, right and left bundle branches, Perkinje fibers
What are the structures involved in the conduction system of the heart?
Internal pacemaker , sinoatrial(sa) node, atrioventricular (av) node , atrioventricular bundle (bundle of his ) and purkinje fibres.
What is the pacemaker for the entire myocardium?
The pacemaker of the entire myocardium is the: a) Atrioventricular junction b) bundle of his c) Purkinje fibers d) Sinoatrial node
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 part of the heart's conduction system acts as the primary pacemaker?
The atrioventricular (AV) node which is located in the right atrium. From there is travels down the septum, also called the atrioventricular bundle, and then spreads to all parts of the ventricles via the Purkinje fibers.
Which fibers spread the electrical signal throughout the ventricular walls?
Purkinje cells are specialized cardiac cells, whose purpose it is to spread the electrical signal from the atrioventricular (AV) node down through the right and left ventricles.
What is the population of Purkinje Incorporated?
The population of Purkinje Incorporated is 100.
When was Purkinje Incorporated created?
Purkinje Incorporated was created in 1985.
