McConnel sign, a simple highly specific sign for identification of a frequent, under diagnosed association: pulmonary embolism and syncope

Syncope is a common reason for emergency room visits and hospital admission and, in about one patient out of six it can be a manifestation of pulmonary embolism (PE). The prognosis of this condition is largely dependent on the timing of diagnosis and treatment since early anticoagulation may modify the clinical consequences of PE and further loss of consciousness. In this article, we describe the case of a woman presenting with syncope, who showed at the admission a cardiac ultrasound highly specific cluster of signs of pulmonary embolism. This rapid non-invasive evaluation permitted to identify causal diagnosis and to speed up the clinical process.
