The cause of dilated cardiomyopathy itself is quite varied including ischemic, infective, valvular, infiltrative, and inflammatory causes. LBBB is prevalent in about 0. In the setting of acute myocardial infarction, there are a set of criteria called Sgarbossa criteria which can be applied to the ECG to increase predictive value for or against myocardial infarction. Epub Aug A ventricular rhythm run of PVCs without super-ventricular stimulation can appear very similar to a left bundle branch block and in certain uncommon situations would be indistinguishable from LBBB. ECGs are definitely a case of improving confidence and knowledge through repeated practice and exposure. Hicks 2.
A useful mnemonic for distinguishing between the ECG patterns of left bundle branch block (LBBB) and RBBB is 'WiLLiaM MaRRoW': WiLLiaM. LBBB: aortic stenosis, dilated cardiomyopathy, MI, CAD. ECG Changes.
