What does the SA node initiate - - P wave (if none, SA not responsible for electrical conduction) (atrial depolarization) What does the QRS complex represent? - ventricular depolarization (vent contraction) (none=no pulse) (don't see atrial repolarization but it occurs, as it is not the strongest thing to occur) What does the U wave indicate? - indicates hypocalemia, not conductio issue it would be seen with electrolyes (digoxin) Is it normal to not see part of the Q, R, or S complex -...

How does sinus block a.k.a. sinus exit block occur? what does it cause? - correct answer When the sinus node fires on time, but the impulse is blocked before it exits the sinus node. This causes a pause that varies in length depending on how many sinus beats are blocked. Will the pause during sinus block be in multiples of the previous RR intervals? - correct answer Yes, Because the SA node is still firing on time. ...
