Key result
Echocardiography captures simultaneous electrical and mechanical alternans in cardiac tamponade.
Why the study?
The true incidence and underlying mechanism of simultaneous electrical and mechanical alternans in pericardial effusion and tamponade were not well documented.
Case Report (n=1)
No takes yet. Share an insight, caveat, or question.
Echocardiographic alternans may aid tamponade recognition; leaves open mechanistic insights from atrial echoes pending prospective validation.
E. Hernandez-Lopez (1980) conducted a case report in Pericardial effusion and tamponade (n=1). Echocardiography was evaluated on Simultaneous electrical and mechanical alternans. Echocardiography documented simultaneous electrical and mechanical alternans in a single case of pericardial effusion and tamponade.
