ECG Abnormalities_Part 14

Wednesday, November 17, 2010

A 72 year old male receives a routine ECG which is below. His electrolytes are normal.

Identify the Abnormality in this ECG strip?

ECG ANSWER

Normal sinus rhythm with a first degree AV block

The PR interval in this ECG is very long, about 380 milliseconds (normal is 120 - 200 ms or 0.12 - 0.20 seconds). A P wave preceeds each QRS complex, thus this is 1st degree AV nodal block.

  25. overall low voltage... looks more like a U wave(in hypokalemia) but since there's no electrolyte disorder, my 2nd guess is 1st degree AV block... QT looks prolonged to me..

  27. Since his electrolytes are normal, U-waves are not suspected; and the fact that the waves are too short, high, and round to be U-waves. Therefore, it's SR with a huge 1st degree AVB.

  29. Prolonged PR interval with no missed beats. 1st degree heart block.

  32. Very interesting blog. A lot of blogs I see these days don't really provide anything that attract others, but I'm most definitely interested in this one. Just thought that I would post and let you know.

     
  33. Interesting. Your instructions look clear but I'm not very good at this so I hope this will work well for me. Thanks for the tips!
