1- Sinoatrial (SA) node- pacemaker
2- Atrioventricular (AV) node
3- AV bundle- Bundle of His
4- Bundle Branches
5- Perkinje Fibers
Cardiac Cycle
P Wave- Atrial depolarization
P-Q Interval- Atrial systole
QRS Complex- Ventricular depolarization begins after Apex
S-T segment- Ventricular Systole
Q-T Interval- Ventricular depolarization through repolarization
Tachycardia and Bradycardia
