Pulmonary Embolism: McGinn-White Pattern

Report:

Sinus rhythm 90/min

Right axis deviation +110o

S1Q3T3 (McGinn-White) pattern consistent with acute cor pulmonale

qR V1 and anteroseptal ST/T changes consistent with right ventricular "strain"

Comment:

The q in V1 may be a sign of right atrial enlargement163.

The pattern of acute cor pulmonale does not necessarily mean pulmonary embolism, but most cases are due to it.

Angiography was performed three days later and confirmed extensive pulmonary embolisation. The cause of this patient's thromboplastic tendency remained unknown. The suspects are many and varied164.
