RSR'

An RSR’ pattern has two positive R waves within the complex. The overall complex may be wide (complete bundle branch block) or narrow (incomplete bundle branch block). If the QRS is wide, this can be a sign of bundle branch block. If the QRS is not wide, it may either be an incomplete bundle branch block or V1 electrode misplacement (usually with T wave inversion in lead V2 and negative P waves in V1).
