In a normal electrocardiogram, the ____.
A. P wave results from repolarization of the atria.
B. QRS complex results from ventricular depolarization.
C. P wave occurs after the QRS complex but before the T wave.
D. T wave represents depolarization of the atria.
E. repolarization of the atria is clearly visible.

Respuesta :

The answer is B.

P wave is depolarization of atria.
QRS is depolarization of ventricles.
T wave is repolarization of the ventricles.
The repolarization of atria is not visible in the normal ECG.

In a normal electrocardiogram, the QRS complex results from ventricular depolarization. Thus, the correct option is B.

What is Electrocardiogram?

An Electrocardiogram may be defined as the process of visualizing or display of a person's heartbeat that is produced by an instrument known as an electrocardiograph. It is a procedure that is utilized when a person is facing difficulty in breathing or may undergo a severe injury.

During a normal procedure of an electrocardiogram, the following outputs are analyzed on the principle of electrocardiography.

  • The P wave results from depolarization of the atria.
  • The QRS complex results from the depolarization of the ventricles.
  • The T wave results from the repolarization of the ventricles.
  • While the repolarization of the atria is not visualized during electrocardiography.  

Therefore, in a normal electrocardiogram, the QRS complex results from ventricular depolarization. Thus, the correct option is B.
