severe lvh left bundle
Left bundle branch block (LBBB): 1) rS complex in V1 (tiny R wave, deep S wave) . Left bundle branch block (LBBB) occurs when something blocks or disrupts the electrical impulse that causes your heart to beat. This block leads to an abnormal heart rhythm. A diagnosis of left bundle branch block often means that you have an underlying heart condition.

Left bundle branch block (LBBB): 1) rS complex in V1 (tiny R wave, deep S wave) 2) Characteristic lateral lead morphology in V5-6. 3) Note appropriate discordance in V1 with ST elevation and upright T wave. What about the ST elevation?The hallmark of left bundle branch block (LBBB) is QRS duration ≥0,12 seconds, deep and broad S-wave in V1/V2 and broad clumsy R-wave in V5/V6. Refer to Figure 1, where the difference between normal conduction, right bundle branch block (RBBB) and left bundle branch block (LBBB) is illustrated. Left ventricular hypertrophy (LVH): Markedly increased LV voltages: huge precordial R and S waves that overlap with the adjacent leads (SV2 + RV6 >> 35 mm). R-wave peak time > 50 ms in V5-6 with associated QRS broadening. LV strain pattern with ST depression and T-wave inversions in I, aVL and V5-6.
The most common causes of left ventricular hypertrophy are aortic stenosis, aortic regurgitation, hypertension, cardiomyopathy and coarctation of the aorta. There are several ECG indexes, which generally have high diagnostic specificity but low sensitivity.Left bundle branch block: Epidemiology, etiology, anatomic features, electrovectorcardiography, and classification proposal.

Left bundle branch block (LBBB) results in an altered pattern of left ventricular (LV) activation and subsequent contraction, causing remarkable changes in LV mechanics, perfusion and workload and ultimately leading to pathologic cardiac remodelling. Left bundle branch block may be due to conduction system degeneration or a reflection of myocardial pathology. Left bundle branch block may also develop following aortic valve disease or cardiac procedures.Left bundle branch block. Electromechanical dyssynchrony. Cardiomyopathy. Left bundle branch pacing. Key points. •. The anatomy of the left bundle branch (LBB) has marked variability between individuals. There are variations in size, branching pattern, .
These abnormal electrical activation patterns, particularly the left bundle branch block (LBBB) pattern, are associated with the presence, development or worsening of cardiomyopathy, and leads to increased risk of subsequent morbidity and mortality.
