Question

Quizplus · Accepted Answer

If both the sinus node and atria fail to generate an electrical impulse, there will be no depolarization of the atria, which is represented by the P wave on the electrocardiogram. The QRS complex and T wave are generated by the ventricles and are not directly affected by atrial depolarization. The R wave is a component of the QRS complex and is also generated by ventricular depolarization.
