2nd degree AV block is not necessarily a pathologic condition in the
horse. It is often found in normal animals at rest, and in my experience,
more frequently in fit horses.
What it is, is a P wave not followed by a QRS complex, or
simplified, a lub without the dub.
In most horses with 2nd degree block, this is found in resting
horses with a normal HR, and is abolished with exercise.
