2009, International Journal of CardiologyCitation Excerpt :There are specific protocols for patients with LBBB on resting ECG, especially for aircrew members, including exercise ECG, Holter ECG, echocardiography, evaluation of CAD with myocardial perfusion scan in subjects aged > 40 years, and an electrophysiological study in the presence of advanced AV-blocks and tachyarrhythmia. However, non-invasive stress tests have a limited performance to identify CAD in patients with complete LBBB [3–7]. In exercise stress test, the interpretation of the ECG is basically impossible because ST-segment changes are non-specific for ischemia [3].
Prognostic Value of Exercise Echocardiography in Patients With Left Bundle Branch Block
2009, JACC: Cardiovascular ImagingCitation Excerpt :Although LBBB may be associated to CAD and other heart diseases, it also may be an isolated finding; thus, diagnostic evaluation and risk stratification of patients with symptoms suggestive of myocardial ischemia are important, given the prognostic implications. Exercise ECG testing is not valid for detecting CAD in these patients (25). Single photon-emission computed tomography also has important limitations; although its sensitivity for the diagnosis of CAD is relatively high, its specificity is low as the result of a high incidence of false reversible perfusion defects, especially in the septum.
