Overview
The EKG in patients with pericardial effusion may demonstrate low voltages (micro-voltages or short QRS complexes) and electrical alternans.
Electrocardiogram
Electrical alternans is an electrocardiographic phenomenon of alternation of QRS complex amplitude or axis between beats. It is seen in cardiac tamponade and pericardial effusion and is thought to be related to changes in the ventricular electrical axis due to fluid in the pericardium.
