         My goal in this 58-minute video series is to review the approach to diagnosing the AV Blocks. This starts with recognizing what AV Block is (and is not— what conditions may mimic AV Block (ie, blocked PACs— and how to distinguish Complete AV Block from AV Dissociation. Focus is on the 3 types of 2nd-Degree AV Block (Mobitz I; Mobitz II; 2-to-1 AV Block— and on how to make a definitive diagnosis of Complete AV Block.
    • Below in Figure 1 — a sample of some issues discussed. I believe this video brings the topic to life!
