Bundle branches are part of the heart's conduction system, specifically responsible for transmitting electrical impulses from the atrioventricular (AV) node to the ventricles. There are two main bundle branches: the right bundle branch, which conducts impulses to the right ventricle, and the left bundle branch, which splits into two further branches to distribute impulses to the left ventricle. This coordination ensures that the ventricles contract in a synchronized manner, allowing for efficient pumping of blood. Any blockages or damage to these branches can lead to arrhythmias or other cardiac issues.

Which structure of the conduction system was formerly called the bundle of His?
The structure of the conduction system formerly known as the bundle of His is now referred to as the atrioventricular (AV) bundle. It is responsible for conducting electrical impulses from the atria to the ventricles of the heart. The AV bundle splits into right and left bundle branches that extend into the ventricles, facilitating coordinated contraction.
If a myocardial infarct destroyed a portion of the right or left bundle branches what potential change might you see in the ECG?
You can see the M pattern in ECG in place of ORS complex. In case of right bundle branch block, you see the M pattern in lead V one. In case of left bundle branch block, you see the M pattern in lead V six.
What is the correct order of stimulation in the nodal pathways?
The correct order of stimulation in the nodal pathways is: 1. Sinoatrial (SA) node generates electrical impulses 2. Atrioventricular (AV) node delays the impulses 3. Bundle of His conducts the impulses to the bundle branches and Purkinje fibers for ventricular contraction.
Is bundle an abstract noun?
yes bundle is an abstract noun
How many bundle branches does the heart have?
There are two bundle branches, right and left.
The correct sequence in the conduction system of the heart is?
SA node, Internodal pathways, AV node, Bundle of His, Bundle branches, Purkinje fibers.
Where do nerve impulses travel from to enter the bundle branches?
Nerve impulses come through the sinus node of the heart to the bundle of His and then move into the right and left bundle branches.
The normal pattern of impulse conduction through the heart is?
SA node, AV node, AV Bundle, Bundle branches, subedocardial branches (purkinje fibers)
What connects atrium s to ventricles?
bundle branches
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 is the function of the bundle branches?
To transfer electrical activity to pakinji mucsles
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 a BBB in the heart?
This si known as a Bundle Branch Block - and refers to an anomaly of a blockage in the nerve system of the heart at the bundle branches.
What is The function of left and right bundle branches?
The right bundle carries nerve impulses that cause contraction of the right ventricle (the lower chamber of the heart) and the left bundle carries nerve impulses that cause contraction of the left ventricle.
What are the five areas of specialized myocardium?
sinoatrial node, right and left bundle branches, atrioventricular node, atrioventricular bundle, ventricular walls.
