Significance of upright t waves in precordial lead V1 as to its correlation with coronary artery disease and in particular the circumflex coronary artery

ABSTRACT

Purpose: The T wave in precordial lead V1 is normally inverted in normal adults. The significance of an upright T wave in precordial lead V1 as to the presence of coronary artery disease is controversial and not well studied in the literature. Our purpose is to show the relation between an upright T wave in V1 and the presence of coronary artery disease and specifically that of the circumflex
