Rate: 65bpm Regularity: regular w/o ectopy P-waves: sinus, 1:1 association PRi: normal QRSd: ~100ms
Rhythm: normal sinus rhythm
Axis: normal, probably ~45deg QTi/QTc: borderline ST/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.
The list of differential diagnoses would include:
ReplyDelete1. Myocardial ischemia/Wellens' warning
2. Benign T-wave inversion / Early repolarization
3. CNS disease
4. Myocarditis
5. Electrolyte disturbance
6. Subacute/old pericarditis
7. Myocardial contusion
8. Myocardial infarction
9. Drug effect
