A weekly ECG / EKG review blog looking at some interesting ECG's from the world of Emergency Medicine.
The list of differential diagnoses would include: 1. Myocardial ischemia/Wellens' warning2. Benign T-wave inversion / Early repolarization3. CNS disease4. Myocarditis5. Electrolyte disturbance6. Subacute/old pericarditis 7. Myocardial contusion8. Myocardial infarction 9. Drug effect
Rate: 65bpmRegularity: regular w/o ectopyP-waves: sinus, 1:1 associationPRi: normalQRSd: ~100msRhythm: normal sinus rhythmAxis: normal, probably ~45degQTi/QTc: borderlineST/T-waves: no elevation, however, deeply symmetric T-wave inversion in the precordials and flat ST-segments with terminal T-wave inversion in I and aVL.DDx: normal sinus rhythm with Wellens T-waves from a recently reperfused LAD; also on the list for me is CNS insult; don't know that I'd include BTWI in a 45yo M (or at least not in the field).As always Jason has a pretty comprehensive list to choose from after you've worked thru the #1 and #2 lethal ones.
