You are a hospitalist at a 50-bed hospital. The 52-year old male below is scheduled for an elective cholecystectomy. The patient developed chest pain the morning of planned surgery and the surgeon has asked you for clearance for surgery. Choose one only
Tracing of the Week (Tracing #34)
A..... The significantly wide Q-wave of lead avR is virtually diagnostic of a right ventricular infarction (old).
B..... Electrical axis between 0 degrees and -30 degrees (approximately -20 degrees).
C..... Significantly wide Q-wave Leads III & avF and with ST elevation concave down, suspicious of the acute inferior MI (STEMI).Hold for surgery until medical clearance.
D..... R = 16 mm in lead avL. Meets voltage criteria of LVH.
E..... ST depressions and T-wave inversion (biphasic) in Leads I, avL, V4, V5, V6 probably secondary to LVH. However, might be reciprocal depressions of an acute inferior MI (STEMI).Hold for surgery until medical clearance.
F..... A, B, D and E only.
G..... A, B and E only.
H..... B, C, D and E only.
I..... C, D and E only.
J..... Sinus tachycardia with non-specific St-T changes (I agree with the computer interpretation and the patient should be cleared for surgery)
