In this episode of Good Reads, we conclude our series on left bundle branch block (LBBB) by exploring Criteria C using the Smith Modified Criteria. We delve into how the ST segment elevation must be 25% or greater in relation to the preceding R wave depth and replace the
outdated 5 mm rule. The video includes a step-by-step example to make this criterion clear. Learn how to identify positive indications for LBBB, especially in challenging environments like an ambulance. Additionally, we touch upon recognizing reciprocal changes and how other criteria (A and B) intertwine.
