What is the normal total delay of the cardiac impulse in the A-V node + bundle?
The impulse from the S-A node travels rapidly through the internodal pathways and arrives at the A-V node at 0.03 second, at the A-V bundle at 0.12 second, and at the ventricular septum at 0.16 second. The total delay is thus 0.16 second
0.22 second
0.18 second
0.16 second
0.13 second
