Patient's clinical data: 47-year-old black man. Another serial ECG (seen below) showed a supraventricular tachycardia (SVT) at a rate of 164/min that was diagnosed by an Electrophysiologist as atrioventricular nodal reentrant tachycardia (AVNRT). How does knowing the mechanism of AVNRT help you in determining the nature of the mechanism in this week's ECG.
Type I A-V block
This ECG was taken from an 87-year-old black man and was diagnosed by the reviewing cardiologist as "complete A-V block".
Is that really the interpretation or is it something else?
A member’s recent comment inspired me to post this ECG. I’ve chosen this topic because there is much confusion and misunderstanding about it.
I recently performed both of these ECGs a few days apart during the same work week. They were recorded on an outpatient basis. It wasn’t until I recorded the second ECG that I realized I had a good pair of ECGs to illustrate this comparison.
