Jason's Blog: ECG Challenge of the Week for Jan. 27th - Feb. 3rd.

Patient's clinical data:  67-year-old white man with a history of COPD and CAD.

Unfortunately, due to the advanced age of this ECG (29-years ago), many details of the device will have to be left to speculation.  I'm unable to retrieve any information about the patient other than the two diagnoses above.

How many different things can you spot in this 12-lead ECG?

Jason's Blog: ECG Challenge of the Week for Dec. 23rd - 30th.

I performed this ECG earlier this year in an outpatient clinic.

Patient's clinical data:  85-year-old white man; asymptomatic. 

Questions?
(1.)  What rhythm is this tracing showing?
(2.)  What clue/sign is used to differentiate between the two anomalous beats (i.e., 4th and 6th beats).  HINT:  It's named after a part of a certain animal's anatomy.

Jason's Blog: ECG Challenge of the Week for Nov. 4th - 18th.

This is a "Routine" resting 12-lead ECG I performed on a patient several months ago in the Outpatient ECG Lab.

PATIENT CLINICAL DATA:
72-year-old white man; asymptomatic; resting comfortably in recumbent position.

This is an exercise in "anomalous" beats.

QUESTION:
(1.)  Specifically, what are 3rd, 4th, and 10th beats?
