Which wave on the EKG represents the firing of both right and left ventricles?

Explanation:
Ventricular activation is shown by the QRS complex. After the atria depolarize (P wave), the ventricles depolarize rapidly as the impulse travels through the His-Purkinje system, producing a sharp, tall deflection—the QRS complex—that corresponds to both ventricles firing in a coordinated way. The P wave represents atrial depolarization, the T wave represents ventricular repolarization (recovery), and the U wave is an extra deflection seen less consistently. So, the QRS complex best reflects the simultaneous firing of both ventricles.
