What does this mean? "there is a shortened p-r interval consistent with an intra-nodal accessory pathway"

Electrophysiology: A short pr interval by itself does not always indicate presence of an accessory pathway. The clinical history your doctor obtains from your can be more important. With that being said, a short pr interval is concerning for wpw, lgl, other pre-exitation syndromes & hcm syndromes. Suggest uploading & sending the ECG to one of the cardiologists on healthtap to obtain an expert opinion.

Nodal conduction: "intra-nodal pathway"? You may have accelerated av nodal conduction from what is thought as inter-nodal pathways - three potential ones- from sinus node to the av node which is likely normal for age. If there is evidence of a delta wave than you may have wpw. Nodofasicular or nodoventricular pathways can give shortened pr intervals. Any palpitations?Have an electrophysiologist review your ecg.

Pathway: presence of an additional pathway, but if you don't have WPW, these short PR intervals are usually not important, best to ask your doc who has seen your ECG.
