This is probably more in-depth than required for the Step 1, but I'd like someone to explain:
1- Why does the QRS complex have two downward waves (Q & S) if it's just depolarization?
2- Why is the T wave in the same recorded direction (upwards) as the R wave, even though the R wave denotes depolarization and the T wave denotes repolarization?
It's easy to just memorize, but since I have some time before I give the exam, I'd like to understand better.
Thanks in advance.
