2024年10月8日 · 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
Left bundle branch block (LBBB): ECG criteria, causes, …
A QRS duration of 120 ms (0.12 s) or more is required to diagnose a complete left bundle branch block. In addition to prolonged QRS duration, LBBB is characterized by deep and broad S-waves in leads V1 and V2 and broad, …
LBBB - ECGpedia
2012年8月25日 · In left bundle branch block (LBBB) the conduction in the left bundle is slow. This results in delayed depolarization of the left ventricle, especially the left lateral wall. The electrical activity in the left lateral wall is …
Left bundle branch block - Wikipedia
LBBB is diagnosed on a 12-lead ECG. In adults, it is seen as wide QRS complexes lasting ≥120ms with characteristic QRS shapes in the precordial leads, although narrower complexes are seen in children. In lead V1, the QRS complex is often entirely negative (QS morphology), although a small initial R wave may be seen (rS morphology). In the lateral leads (I, aVL, V5-V6) the Q…
