My older sister (a health nut) was diagnosed with left bundle branch block (LBBB) some years ago, and after she had all the appropriate diagnostic tests (in her case, gated-SPECT scan with Myoview, and an echocardiogram) performed, it was deemed benign/harmless (possibly she was even born with it, though she had no other previous ECGs to compare it to, no baseline).

LBBB, is a commonly seen electrical conduction abnormality during a routine resting electrocardiogram (ECG/EKG), that is often associated with coronary artery disease (CAD), though can occur in some heart-healthy individuals.
