In brief: Depends on the cause

First degree heart block is actually a misnomer as there is no conduction "block".
The more accurate term is prolonged av conduction and this may be the result of medications, metabolic derangements or thyroid disease. Correcting the medication dose or type may correct the first degree heart block. Often times the first degree heart block occurs for unknown reasons and does not correct.

First degree heart block may be a physiologic response to increased vagal tone and as such, it may be transient. In my experience, first degree block is most often associated with medications and is almost never a clinical problem.

In brief: First degree

First degree av block is slowing in conduction from the atria to the ventricles.
On an ECG it manifests as a prolonged pr interval. In some cases it can reverse, in general it has no associated symptoms.
