Heart How do we get Electromechanical Dissociation?

Hi all:

There is an UW explanation saying that examples of electromechanical dissociation are pulmonary thromboembolism and cardiac tamponade.
Can someone please explain what is the association between electromechanical dissociation and pulmonary thromboembolism and cardiac tamponade?

Thank you!

Anything that can lead to massive decrease in CO with the heart being normal (i.e not damage) can lead to EMD where ecg document normal cardiac activity but actually there's no pulse palpated cuz no blood is being pumped by heart
The mcc are MASsive PE or tamponade

i think this is mainly "pulseless electrical activity" and what you do next is control the underlying cause like PE/tamponade and initiate CPR.
