Sinoatrial exit block is due to failed propagation of pacemaker impulses beyond the SA node. An outer layer of transitional cells T cells that transmit the sinus impulses out into the right atrium. Sinus node dysfunction can result from either: Failure of the P cells to produce an impulse. This leads to sinus pauses and sinus arrest. Failure of the T cells to transmit the impulse. This leads to sino-atrial exit block.

AU — Maione, S. I am guessing that because they are using the word run, they are referring to what we call supraventricluar tachycardia or SVT. AU — Adinolfi, L. Le bloc sino — auriculaire et les maladies du sinus. Therefore, if there is no electrocardiographic evidence of an accessory pathway, far from indicating accelerated conduction, the short PR may be due to an isolated defect of conduction in the atrial myocardium, as Condorelli suggested.

I suspect that you are at some statistically elevated risk of a blood count compared to someone who does not have anticardiolipin however, I do not think that your described PACs should be problematic Good Luck Note added at 53 mins Images in this article Image on p.

Peer comments on this answer and responses from the answerer agree. This study suggests that it is useful to separate those cases with a short PR and normal QRS into a clinical entity of their own, as this syndrome may have a different pathogenesis.
