Web20 jun. 2024 · The left bundle is composed of two fascicles (the left anterior and the left posterior fascicle) Normally, the left bundle depolarizes the left ventricle. In a LBBB, the left bundle does not activate. The left ventricle is, instead, depolarized by spread of impulse from the right bundle through the RV and then to the LV. Web17 feb. 2016 · However, the earliest findings on an ECG are subtle changes in the T-wave shape and size. When a coronary artery is occluded, within the first 30 minutes, the T-wave amplitude increases [2]. The next changes are ST-segment elevation and loss of the R-wave amplitude. If the vessel remains occluded, Q-waves develop.
