Given below is the ECG of a normal human. Which one of its components in humans is correctly interpreted below? <img class="img-fluid question-image" alt="Question" src="https://cdn.tardigrade.in/q/nta/b-evrcbiacmewknlfz.jpg" /> (A) Complex QRS - One complete Pulse. (B) Peak T - Initiation of total cardiac contraction. (C) Peak P and Peak R together - Systolic and diastolic blood pressures. (D) Peak P - Initiation of left atrial contraction only.

The given diagram represents ECG. The

P is the atrial systole. This also depicts the contraction pulse.
QRS complex represents ventricular depolarization. This completes one pulse. This complex represents the ventricular systole.
T is the recovery of the ventricles. This represents complete repolarisation.

Q. Given below is the ECG of a normal human. Which one of its components in humans is correctly interpreted below?

Complex QRS - One complete Pulse.

Peak T - Initiation of total cardiac contraction.

Peak P and Peak R together - Systolic and diastolic blood pressures.

Peak P - Initiation of left atrial contraction only.
