Answer:
Yes, the blood pressure and heart rate return to normal after 5 minutes of physical exercise as, ANS will detect the decreasing level of oxygen and activate parasympathetic system to normalize the heart rate. The increasing of heart rate does not cause the blood pressure to increase at the same rate. After 5 minutes it return to normal as when you exercise heart rate speed up so that is why more blood reach in the muscles so it cause high heart rate and blood pressure for some minutes.

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.
