Finally, the decision making rules using the ECG features for the detection of RBBB and LBBB are implemented. The implementation is done in MATLAB environment. The experiments are carried out on MIT-BIH database. The results show that our proposed method is very effective and an efficient ...
Abbreviation: RBBB A defect in the conductive system of the heart in which electrical conduction down the right bundle branch is delayed. On the 12-lead EKG, it gives the widened QRS complex an RSR appearance in leads V1 and V2. left bundle branch block Abbreviation: LBBB A defect in ...
The ECG strip below shows normal sinus rhythm, then atrial fibrillation with a rapid ventricular response develops. With the faster heart rate, the QRS complex morphology changes to that of a LBBB. As sinus rhythm restores, and the ventricular rate slows, the QRS morpho...

ECGLBBBRBBBAn 86-year-old female with aortic stenosis was qualified for invasive correction of the valvular heart disease. She developed a severe ventricular hypertrophy (LVH) and had an intermittent left bundle branch block (LBBB) and right bundle branch block (RBBB). We report the case of a...
(81% vs. 66%) but in RBBB only the prevalence of severe LVSDF had increased in the prolonged QT interval subgroup. (21% vs. 12%). In patients with BBB, especially LBBB, there is a direct significant relationship between prolonged QT interval and...
