What will happen if the neuromuscular conduction pathway in heart is broken between SA node and AV node?
1 No contraction or heart beat will be seen in heart.
2 Auricles will contract due to impulse generated by SA node while ventricles will not show any activity.
3 There will be no effect on the activity of heart.
4 Auricles will contract at the rate set by the SA node while ventricles will contract at the rate of impulse generated by the AV node.
Explanation:
If the neuromuscular conduction pathway in heart is broken between SA node and AV node then auricles will contract at the rate set by the SA node while ventricles will contract at the rate of impulse generated by the AV node.
