Cardiac tamponade electrocardiogram

Electrocardiogram

Tamponade may be associated with ST segment changes on the electrocardiogram ^[1]. Given the insulating properties of the fluid, there may also be low voltage QRS complexes ^[2]. In some cases, electrical alternans will be present in which case the height of the QRS varies from beat to beat. Tachycardia will likely be present as well.
