QUESTIONS???? 1.What is the major abnormality on this ECG? 2.How would you interpret this ECG? QUESTIONS???? 1.What is the major abnormality on this ECG? 2.How would you interpret this ECG? 3

Let’s start with the rhythm. What would you say? 4 There are p waves with each QRS but look at the rhythm strip. It appears that there is a different pacemaker established during this rhythm strip This is an atrial escape rhythm and it has a different atrial focus and different rate than the preceding rhythm The p waves change morphology at the same time the rate markedly changes

The rate appears to be approximately 75 bpm in most of the tracing 5 The axis appears to be normal since it is upright in both leads I and II The PR/QRS/QT intervals appear WNL although precise measurement is difficult because of the quality of the ECG copy There are no signs of hypertrophy There are no suspicious q waves. Good r wave progression is present. There are no changes of ST segment depression. Finally, there are no inverted T waves or T wave flattening to suggest any specific abnormality.

6 FINAL REPORT ECG shows sinus rhythm with an atrial escape rhythm. Axis is WNL. PR/QRS/QT intervals appear WNL. No evidence of hypertrophy. No abnormal ST/T wave changes. FINAL REPORT ECG shows sinus rhythm with an atrial escape rhythm. Axis is WNL. PR/QRS/QT intervals appear WNL. No evidence of hypertrophy. No abnormal ST/T wave changes. That concludes the Underwriting Puzzler. Thank you!
