Key Points Progressive PR Lengthening: PR interval gradually increases before a non-conducted P wave (dropped beat). Regular P Waves: P-P interval is generally constant; slight variations may occur due to…
Key Points Definition: Mobitz II is a type of second-degree AV block characterized by sudden failure of conduction after a constant PR interval, without progressive prolongation. Constant PR Interval: PR…
Key Points Definition: A type of second-degree AV block where every other P wave is non-conducted, resulting in a 2:1 conduction pattern. Diagnostic Challenge: Difficult to differentiate between Mobitz I…
