17. Gail Walraven, Basic Arrhythmias, Sixth Edition ©2006 by Pearson Education, Inc., Upper Saddle River, NJ Normal 12-Lead EKG  All waves upright (except aVR)  Small Q waves in lateral leads (I, aVL, V 6 )  All T waves smooth, gradual  T wave: positive, negative, or biphasic in V 2 ; positive in V 2 –V 6  V 1 : small R, deeper S (rS)  V 6 : tall R, small S (Rs)  Transition (equiphasic RS) occurs in V 3-4
