The normal electrical conduction in the heart allows the impulse that is generated by the sinoatrial node (SA node) of the heart to be propagated to, and stimulate, the cardiac muscle (myocardium).

On the ECG, the time necessary for the spread of an electrical impulse through the AV node, bundle of His, right and left bundle branches, and the Purkinje fibers is reflected by the?

Under normal conditions, electrical activity is spontaneously generated by the SA node, the physiological pacemaker. This electrical impulse is propagated throughout the right atrium, and through Bachmann's bundle to the left atrium, stimulating the myocardium of the atria to contract. The conduction of the electrical impulse throughout the atria is seen on the ECG as the P wave. As the electrical activity is spreading throughout the atria, it travels via specialized pathways, known as internodal tracts, from the SA node to the AV node.

In order to maximize efficiency of contraction and cardiac output, the conduction system of the heart has: 1  Substantial atrial to ventricular delay. 2  Coordinated contraction of ventricular cells. 3  Ventricular contraction begins at the apex of the heart, progressing upwards to eject blood into the great arteries. 4  Depolarization propagates through 5  ...

A skeletal muscle contracts only after it is stimulated by a nerve. 2. Heart has pacemaker cells that can generate an electrical impulse without being stimulated by a nerve. a. ability of cardiac pacemaker cells to create an electrical impulse without being stimulated from another source is called automaticity.
