ECG Challenge donated by Guru member "chireu".

This is a derived (i.e., EASI) 12-lead ECG donated to the ECG Guru by new member "chireu".  The only history they were able to provide was one of possible atrial flutter but that was uncertain.  How would you interpret this ECG?

This is an ECG I performed a couple of years ago on an asymptomatic 83-year old man as an outpatient procedure. 

The computer interpreted this as:  "Marked sinus bradycardia [with] Frequent Premature ventricular complexes".  IS THE COMPUTER CORRECT?  Is there more than one plausible interpretation?  What is the differential diagnosis?

Jason's Blog: ECG Challenge for the month of June, 2014.

This is an ECG I performed on a 65-year old man about 5 years ago.  He mentioned something to me about his past medical history before we got started but, in truth, I would have recognized it had he not told me beforehand.  What did he tell me and what does this ECG reveal?

Jason's Blog: ECG Challenge for the month of May, 2014.

Patient data:  54-year old man who recently underwent a major cardiac procedure.  At first glance, this ECG may not appear to be particularly unique but a closer inspection reveals something unusual going on here. 

HINT:  The telling clue can be found in lead II but you'll have to use calipers and think "outside-the-box".  3 days after this ECG, the patient reverted back to sinus rhythm but continued to display this one finding.  Good luck!

All depends on how you define "degrees" - Winter Edition.


This is a contrasting follow-up to a posting I made during the record-setting heat of 2012's summer.  Today, one of our local news channels here in Richmond, Virginia was reporting on widespread normal axis throughout central Virginia.  Note the isolated physiological left axis deviation in the ironically-named “Hot Springs” Virginia.
