How is a cardiac impulse, conducted in heart?

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.

The speed at which impulses are conducted increases with:

Where does cardiac impulse originate. How is it conducted to the rest of the chambers.

Find out the correct sequence of transmission of cardiac impulse in heart during a cardiac cycle.

Cardiac muscles are found in __ of the heart

The cardiac impules that results into the heart beat is delayed at :-

Which of the Following takes place during impulse conduction during depolarisation of nerve impulse -

Go through the following statements (i) The inner surface of atria have got transverse muscular ridges called papillary muscles. (ii) Chordae tendinae are special fibrous cords attached to the AV valves and prevent them from collapsing back into the atria during powerful vantricular contraction (iii) The neurogenic heart stops functioning immidiately after removal from the body. (iv) The conduction of cardiac impulse is slowest in the A.V. node. Which of these are correct ?

Which set of ions is necessary for the nerve impulse conduction ?

The cardiac impulse is initiated and conducted further upto ventricle. The correct sequence of conduction of impulse is
