Pathophysiology
         
VEB Couplets     C9, C10, C11, C15, C25, C26, C27, R22

Two sequential VEB's preceded and followed by at least one (1) Normal Sinus Beat; i.e., "NVVN", where N=Normal Sinus Beat, and V=VEB. For couplet recordings, multiformity is determined by the shape of any isolated VEB's and the shape of the first complex only of any couplets. The form of the second complex is ignored.
