The AV node normally initiates the cardiac impulse.

Text Solution

AI Generated Solution

To determine whether the statement "The AV node normally initiates the cardiac impulse" is true or false, we can analyze the process of how the cardiac impulse is generated and propagated through the heart. ### Step-by-Step Solution: 1. **Understanding Cardiac Impulse**: - The cardiac impulse refers to the electrical signals that trigger the contraction and relaxation of the heart muscles, leading to the cardiac cycle, which consists of diastole (relaxation) and systole (contraction). 2. **Identifying the Pacemaker**: ...

In cardiac muscle

Assertion : The AV bundle is essential for the conduction of cardiac impulse. Reason: There is no continuity between the cardiac muscle fibers of the auricles and those of the ventricles.

Cardiac muscle is:

Which of the following structures in the normal human heart generates action potential to initiate a cardiac cycle?

What is cardiac output ?

Assertion : The AV node is also called as the pacemaker of the heart. Reasoning : It is because of the fact that the AV node determines the rate of heartbeat.

Assertion : The cardiac impulse is said to be myogenic. Reasoning : The rate of formation and conduction of cardiac impulse can be changed by the action of nerves.

Read the following statements (i) The nodal musculature of the heart has the ability to generate action potentials without any external stimuli. (ii) The AV node is located in the right ventricle close to the AV septum (iii) The stroke volume is the amount of blood pumped out by each ventricle per minute. Which of these are correct ?

The atrial systole normally precedes the ventricular systole because the impulse takes time to pass from

A : The cardiac impulse which originates from SA node in mammalian heart cannot spread directly from atria to ventricles R : In mammalian heart there is no continuity between cardiac muscle fibres of atria and those of ventricles except AV bundles.
