Answer :
Answer:
QRS complex.
Explanation:
The electrocardiogram may be defined as the medical technique used for the proper functioning of the heart. The electrodes are inserted on the chest of the individual to determine the conductivity changes in the heart.
The report of the ECG is prepared in the peaks form. The different components includes the P, QRS, PQ and ST segment. The QRS complex shows the ventricular depolarization in the normal heart. If the ventricular depolarization gets slow, the QRS complex shape will get change.
Thus, the answer is QRS complex.
