Question. Sinus Rhythm with 2nd degree block type 1

I had an echocardiogram last week. Immediately following the echocardiogram, I asked the technician if I was in afib, to which she replied in the affirmative. At my appointment the following day with the PA, he also stated that I was in afib. When I reviewed the results online myself, I noted this on the report: "Rhythm: NSR". The PA added a note to me on the report: “No significant concerns, thank you!” I sent the PA a note back asking for clarification on the discrepancy between the verbal confirmations that I was in afib and the report stating NSR. He stated, “On first glance, it looks like atrial fib but on further examination and looking at it closer, it actually is a sinus rhythm. It's not a normal SR because you have a second degree block which is nothing to worry about. The official name for your rhythm is Sinus Rhythm with 2nd degree block type 1. It sounds bad but it isn't. Now it's probably clear as mud isn't it.”

The PA is correct, it’s clear as mud. Anyone with experience having a “Sinus Rhythm with 2nd degree block type 1”? Thank you.

"A second-degree type I AV block occurs when conduction within the AV node itself is delayed in this progressive manner. It does not necessarily indicate intrinsic conduction disease, and rarely requires a pacemaker to be implanted. A second-degree type I AV block can be caused by AV blocking medications or increased vagal tone. AV nodal ischemia during an inferior MI can cause AV nodal blocks, as well."


"Common drugs that induce atrioventricular (AV) block include beta-blockers, calcium channel blockers, antiarrhythmics, and digoxin. Withdrawal of the offending drugs is the first treatment for heart block. " Source: [emedicine.medscape.com].
