A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. This term can be confusing, as not all ECG leads contain all three of these waves ...
The QRS axis is the most important to determine. However, the P wave or T wave axis can also be measured. To determine the QRS axis, the limb leads (not the precordial leads) need to be examined.
