B)QRS complex.
C)T wave.
D)P wave.

Question

Quizplus · Accepted Answer

The width of the QRS complex is the major EKG finding that can help distinguish between supraventricular and ventricular rhythms. In supraventricular rhythms, the QRS complex is usually narrow (less than 0.12 seconds) due to the initial activation of the ventricles via the normal conduction system. In contrast, ventricular rhythms have wide QRS complexes (greater than 0.12 seconds) as the ventricles are activated via the slower myocardial conduction system.
