name and describe each part of the wave

1. P wave- atrial depolarization
2. P-Q Interval: time it takes for the electrical conduction (excitation) to travel through the atria and AV node to the purkinje fibers
3. QRS Complex: ventricular depolarization that spreads from the AV node, AV Bundle, right and left bundle branches, and to the purkinje (conduction) fibers just before the ventricles contract. Atrial repolarization
4. S-T Segment: time the ventricular fibers are fully depolarized
5. T wave: ventricular repolarization (just before ventricles relax)
6. Q-T interval:beginning of ventricular depolarization until the end of ventricular repolarization
