Q. What is AV Block ?

First Degree AV Block

At rest commonly disappears with exercise owing to the vagal withdrawal. The development of a prolonged PQ segment after exercise has been reported in patients with triple vessel disease.

Second Degree AV Block

Absence of this type of abnormality in exercise testing is probably due to the fact that we rarely exercise a patient with a known infection or active rheumatic fever. Although second degree AV block probably should be an indication for discontinuing exercise, it is not likely to lead to serious trouble.
