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

A bundle branch block is a blockage in either the right or left bundle of the conducting pathway (see above). Because of the block, the electrical signals that stimulate the ventricles to contract together, are now out of sync.

Right bundle branch block (RBBB) is due to an anatomical or functional dysfunction in the right bundle branch, such that the electrical impulse is blocked. Figure 1 illustrates the components of the ventricular conduction system, including the right bundle branch (RBBB).

2024年10月8日 · RBBB: Right Bundle Branch Block V1: RSR’ pattern in V1, with (appropriate) discordant T wave changes V6: Widened, slurred S wave in V6. Associated features incude: Appropriate discordance with ST depression and/or T-wave inversion in …

For example, an EKG tech can identify a right or left bundle branch block utilizing Lead V1. Multiple leads also help to confirm an anomaly or rule out artifacts. Note that the leads do change depending on the source data.

Right bundle branch block (RBBB) RBBB may be a normal variant – especially if the pattern is present but with a normal QRS duration. Otherwise it may indicate problems with the right side of the heart.

2021年4月28日 · People may have flipped waves in certain leads at baseline after a heart attack, with a bundle branch block, or with a PVC, VTACH, or ventricular paced rhythms. Tall or tented T waves are those that are > 1 large box in lead II and may be particularly pointed.

2022年6月9日 · What is a Bundle Branch Block? A BBB is a conduction block in one of the bundle branches. When such a block exists, the ventricles fire more slowly as the impulse has to travel cell to cell through the muscle wall instead of through the conduction system.
