EKG Patterns 1st & 2nd Degree AV Node Blocks

The video tutorial explains AV node blocks, focusing on first and second degree types. It details how to identify these blocks using ECG patterns, emphasizing the PR interval's role. First degree blocks have an extended PR interval without missing QRS complexes, while second degree blocks are characterized by dropped QRS complexes. Type 1 second degree blocks show an increasing PR interval, whereas Type 2 maintains a constant PR interval. The tutorial also covers quantifying these blocks, providing a comprehensive understanding of AV node block identification.
