Vedclass · Answer

(B) The $ECG$ (Electrocardiogram) represents the electrical activity of the heart.$1$. The $P$ wave represents the electrical excitation (or depolarization) of the atria,which leads to the contraction of both the atria.$2$. The $QRS$ complex represents the depolarization of the ventricles,which initiates the ventricular contraction. This process occurs as the action potential is conducted from the $AV$ node through the Bundle of His and into the Purkinje fibers,causing the ventricles to contract.$3$. The $T$ wave represents the return of the ventricles from an excited to a normal state (repolarization). The end of the $T$ wave marks the end of systole.Therefore,the conduction of the action potential from the $AV$ node to the Purkinje fibers corresponds to the $QRS$ complex.

Which wave is produced when the action potential is conducted from the $AV$ node to the Purkinje fibers?
