Left Bundle Branch Block Cedars-Sinai
Left anterior fascicular block (LAFB) is an abnormal condition of the left ventricle of the heart, related to, but distinguished from, left bundle branch block (LBBB). It is caused by only the left anterior fascicle – one half of the left bundle branch being defective. It is manifested on the ECG by left axis deviation. It is much more common than left posterior fascicular block. WitrynaRight bundle branch block comes from a problem with the heart’s ability to conduct electrical signals. It usually doesn’t cause symptoms unless you have some other heart condition. Your heart has 4 chambers. The 2 upper chambers are called atria. The 2 lower chambers are called ventricles. In a healthy heart, the electrical signal for your ... stepforth publishing pty ltd

The depolarization wave spreads towards the epicardium first, which creates a small positive deflection in the inferior leads (Figure … step for toyota tacoma
