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.
Beginning with this ECG of the Week, I’m going to start routinely presenting these as multiple choices in order to try and encourage more active participation from ECG Guru members. I copied the idea from one of Dr. Wang’s ECGs that was posted on Medscape 8 years ago.
This was one of five consecutive ECGs that I performed on a patient a month or two ago.
Patient’s clinical data: 68-year-old white man with unremarkable cardiac history. After his primary care provider (PCP) detected a slow and irregular pulse on this patient, she sent him over to me, in the Outpatient EKG Lab, to perform a “routine” 12-lead ECG.
Pick the answer that you feel best describes what is seen in the ECG above:
(1.) Starts out as Type II, converts to Type I, and then reverts back to type II AV block
(2.) Type I AV block all throughout
(3.) Type II AV block all throughout
(4.) Neither Type I nor Type II, but a genre all its own
(5.) This may be Type I or Type II, but you cannot tell which one it is
