First-degree AV block occurs most commonly at the level of the AV node and occasionally within the atrium or the His-Purkinje system. On the ECG, it is represented by a prolongation of the PR interval (Fig. 10-13). Common causes of first-degree block are enumerated in Box 10-7.
What causes AV block 1st degree?
First-degree heart block may be caused by: Natural aging process. Damage to the heart from surgery. Damage to the heart muscle from a heart attack.

ICD-10-CM code Z95. 0 is used to report the presence of a cardiac pacemaker without current complications. If the device is interrogated, code Z45. 018 would be reported as it is no longer just the presence of the device but attention to the device.
How do you treat first-degree AV block?
In general, no treatment is required for first-degree AV block unless prolongation of the PR interval is extreme (>400 ms) or rapidly evolving, in which case pacing is indicated. Prophylactic antiarrhythmic drug therapy is best avoided in patients with marked first-degree AV block.
