Electrical alternans is an electrocardiographic phenomenon of alternation of QRS complex amplitude or axis between beats. It is seen in cardiac tamponade and is thought to be related to changes in the ventricular electrical axis due to fluid in the pericardium.
The presence of micro-voltage and electrical alternans suggests pericardial effusion and cardiac tamponade.
