S1 Q3 T3 Pattern: Sensitivity and Specificity

Introduction: None written. Excerpt from the entry in Pulmonary Embolism:
S wave in I, Q wave in III, and inverted T in III

pooled from reproduced data - sensitivity ranges 12-50% in different series

Interestingly, despite the classical description of this feature as representing right heart strain, it was not predictive of massive PE in this case series.
