With progressive delay in depolarization of the right ventricle, vector 2b follows vector 2a rather than occurring with vector 2a. WebThis suggests beat 4 is conducted with a right bundle branch block (RBBB) pattern. QRS morphology of beats 5 and 6 in the long lead II rhythm strip is similar to the QRS morphology of beat 4 that we know is conducted.
