Dilated cardiomyopathy secondary due to MI is the most ominous sign of pulsus alternan.
Your answer of tamponade is correct but tamponade is hardly an ominous sign !
Ominous sing means you are at the DEAD BED and dying NOW !
You are going to die means ominous sign !
Clearly tamponade is not the ominous sign !
