What degree is LBBB?

Left bundle branch blocks (LBBB) are a frequent electrocardiographic (ECG) anomaly that occurs when the His-Purkinje system’s standard cardiac transmission down both front and downstream left fascicles is disrupted. While LBBB is frequently linked with severe cardiac illness and is generally the consequence of myocardial damage, stress, or hypertrophy, this can further be found in people who have no other symptoms.
