James Beckerman, MD, FACC responded:
An ECG can identify a LBBB, but other testing is sometimes performed to look for underlying structural heart disease, based on the specific situation. An echocardiogram (ultrasound of the heart) can provide lots of information in this type of situation and can sometimes guide future testing.
