Acute Cor Pulmonale
Report:
Sinus tachycardia 113/min
S1Q3T3 (McGinn-White) pattern
Incomplete right bundle branch block
Right precordial T wave inversion & ST segment depression
Consistent with acute cor pulmonale
Comment:
The classical S1Q3T3 (McGinn-White) pattern of submassive pulmonary embolism may represent a forme fruste of left posterior hemiblock69; to tell the truth, its genesis is far from understood (by me, at least). Similarly, the right precordial T wave inversion, while certainly a marker of extensive embolism70, does not have a clear-cut explanation. I once tried to relate it to the coexisting or preceding LPHB71, but now I think itâs weak.
The patientâs only risk factor was a trip to Canada and back to Australia.
