Page 51 - Simplicity is Key in CRT

Conclusions
Classification of LBBB on the ECG is not straightforward at all. There is considerable difference in identification of LBBB by the clinical judgement of experienced cardiologists as well as between current LBBB definitions. Furthermore, clinical judgement of LBBB correlates poorly with any of the LBBB definitions. These data indicate that great variability in LBBB classification is bound to be present between clinical trials and between physicians selecting patients for CRT in daily clinical practice.
