Absence of septal Q waves an important predictor of significant coronary artery disease and mainly proximal stenosis of the left anterior descending artery

ABSTRACT

Aims: Data concerning the correlation between the absence of septal q waves and significant stenosis of proximal left anterior descending [LAD] artery shows conflicting results. This retrospective study was conducted to show that absence of septal q waves in leads V5-V6 could be of value in predicting significant coronary artery disease [CAD] and mainly significant proximal LAD coronary artery stenosis
