Second Degree Heart Block Diagnosis: Understanding the Types and Patterns
Here, the PR interval remains constant and normal on the ECG until a beat is suddenly and unexpectedly dropped without any preceding prolongation. It is frequently transient, caused by factors like increased vagal tone, certain medications, or acute myocardial infarction, and often resolves once the underlying trigger is addressed.
This condition requires careful evaluation because it sits between the benign irregularities of first-degree block and the life-threatening complete heart block. This progression can lead to severe bradycardia, syncope, or sudden cardiac arrest, making it a condition that frequently requires immediate intervention with a pacemaker.
Second Degree Heart Block Diagnosis: Understanding the Types and Patterns

This pattern creates a repeating cycle where the R-R interval gradually shortens until a P wave appears without a corresponding QRS complex.
