Sinus node 
The intrinsic pacemaker. Cell membrane "leakiness" causes spontaneous depolarization at a rate 
of 60-100 times a minute. 
AV node 
Acts like a resistor to slow the impulse allowing time for the atria to completely contract before 
initiating ventricular contraction. Back up pacemaker if SA fails, pacing at a rate of 40-60 times 
a minute. 
Bundle of his 
"Cable" that passes through the fibrous sheath separating atria from ventricles. Divides into th...
