Key result
Echocardiography reveals abnormal diastolic septal motion during inspiration in pulsus paradoxus, suggesting shared haemodynamics.
Why the study?
Abnormal and exaggerated diastolic motion of the interventricular septum during inspiration and its relationship with pulsus paradoxus in patients without heart disease was not well characterized.
Case Report (n=1)
Echocardiography can detect abnormal interventricular septal motion during inspiration as a sensitive indicator of the hemodynamic variations associated with pulsus paradoxus.
May aid noninvasive pulsus paradoxus evaluation; hypothesis-generating for shared septal mechanisms, requiring prospective validation.
We report on a patient without heart disease who had pulsus paradoxus, associated with echocardiographic evidence of abnormal and exaggerated diastolic motion of interventricular septum. Both phenomena appeared at the peak of the inspiratory phase of respiration, and seemed to be produced from the same haemodynamic variations, of which the echocardiographic pattern appears to be a more sensitive index than the sphygmographic one.

Ieri et al. (1980) conducted a case report in Pulsus paradoxus (n=1). Echocardiography during inspiratory phase was evaluated on Abnormal diastolic motion of interventricular septum. Echocardiography revealed abnormal diastolic motion of the interventricular septum during inspiration in a patient with pulsus paradoxus, suggesting a shared haemodynamic mechanism.
