Answer #1

Answer: B. Q wave.

Explanation:

The second wave is the QRS complex. Commonly this complex has a progression of 3 avoidances that mirror the current related with right and left ventricular depolarization. By tradition the primary diversion in the complex, in the event that it is negative, is known as a Q wave. The primary positive avoidance in the complex is called a R wave. A negative diversion after a R wave is called a S wave. A moment positive avoidance after the S wave, if there is one, is known as the R' wave. Some QRS buildings don't have every one of the three diversions.
