  • Nausea.
  • Severe tiredness (fatigue)

What happens in second-degree heart block type 2?

Mobitz II second-degree AV block is characterized by an unexpected nonconducted atrial impulse, without prior measurable lengthening of the conduction time. Thus, the PR and R-R intervals between conducted beats are constant.

What is Wenckebach block?

Mobitz type I, also known as Wenckebach block, is a type of 2nd degree AV block, which refers to a cardiac arrhythmia that reflects a conduction block at the atrioventricular AV node.

How common is Wenckebach?

For someone like you, a trained athlete with a slow heart rate, Wenckebach is common (about 10 percent of trained athletes). Since you have no symptoms, I agree with your cardiologist completely and can reassure you that the chance of developing worse heart block is low.

Does Wenckebach go away?

The P–R interval decreases and the Wenckebach block disappears with increased activity, and is considered normal vagal influence on the AV node. Acquired complete heart block is rarely seen in young adults without heart disease.

Which conditions does a type 2 AV block have a very serious prognosis?

Damage to the heart from surgery. Damage to the heart muscle from a heart attack. Other types of heart disease that damage the heart muscle. Low thyroid levels.
