What is the significance of transient abnormal Q-waves during exercise testing with a stenosis of the main stem of the left coronary artery?
West JN, Bennett MR, and Pentecost BL conducted a study to investigate the association between transient abnormal Q-waves during exercise testing with a stenosis of the main stem of the left coronary artery. The study found that the presence of transient abnormal Q-waves during exercise testing was significantly associated with a stenosis of the main stem of the left coronary artery. This suggests that the presence of transient abnormal Q-waves during exercise testing can be used as an indicator of left main coronary artery stenosis.
