Electrocardiography (ECG) is a simple, noninvasive tool to identify cardiac conduction abnormalities. Bundle branch blocks are frequently associated with various medical conditions, some of which could be life threatening if not treated. Right bundle branch block is relatively common when compared to left bundle branch block. Echocardiography is helpful for identifying any structural abnormalities in order to ascertain the prognostic significance of a bundle branch block. Diagnostic tests such as nuclear stress test, multislice computed tomography coronary angiogram, and even invasive coronary angiogram, may be indicated in selected patients.
