swinging heart

A fanciful synonym for the EKG findings in electrical alternans, characterised by a regular alteration in the direction and/or amplitude of one or more components of the EKG reading—e.g., simultaneous oscillation of the P waves, QRS complexes, and T waves—total electrical alternans; these features are highly characteristic of cardiac tamponade
