The electrocardiographic diagnosis of ischemic heart disease is made more difficult in the setting of confounding patterns, including left bundle branch block (LBBB). The electrocardiographic detection of abnormalities arising from acute ischemic cardiac disease in this setting is possible in certain cases, contrary to popular medical opinion. Several strategies are available to assist in the correct interpretation of the electrocardiogram (ECG) with LBBB and potential acute ischemia, including: (1) a knowledge of the anticipated ST segment-T wave morphologies of LBBB and, consequently, the ability to recognize ischemic changes; (2) the performance of serial ECGs demonstrating dynamic change; and (3) a comparison to previous ECGs. The first strategy, an awareness of the anticipated ST segment morphologies of LBBB, is the most important and not dependent on additional diagnostic testing or past medical records.
