What does intermittent Mobitz refer to?

• A. A temporary bundle branch block
• B. A complete heart block
• C. A permanent bundle branch block with intermittent block of the other side
• D. A variant of atrial fibrillation

Answer: (C)

Intermittent Mobitz refers to a classification of heart block where there is a recurring pattern of conduction failure. In this case, it describes a permanent bundle branch block that intermittently experiences blocking of the other bundle branch. This situation can be observed when one bundle branch is already blocked permanently while the other may exhibit transient or intermittent blocks, leading to a fluctuating pattern in the conduction through the heart's electrical system.

Understanding Mobitz blocks is crucial in recognizing their implications on cardiac function. In clinical practice, identifying the nature and pattern of these blocks can help inform treatment decisions and predict the potential risk of further complications, such as complete heart block.
