Brief Answer:
I explain as follows.

Detailed Answer:

Hello,

When considering right bundle branch block (complete or incomplete), the elements to be analysed are the waves of QRS complex.

Regarding your uploaded ECG, it can be noticed that the QRS complex is composed of two positive waves (deflections), which are named r and r1. In between them, there exists a negative wave, below the isoelectric line, which is called s wave.

The above pattern is typical of right bundle branch block. Whether complete or incomplete, it will depend on the QRS width.

I am sorry, but the doctors cannot upload photos or modify them on this site. Anyway, you can find many images of right bundle branch block on Google.

Hope you will find this answer helpful!
