"Does anyone know why this is?"

There's no way to truly know/determine for sure via the Internet.

In general-only here, cardioversion carries risks, and the possibility of complications, some unforeseen. And, as applicable to the patient, there is always the possibility of the present medical condition suddenly worsening (example, congestive heart failure), or complications/side effects/adverse reactions occurring from general anesthesia, I.V. administered and orally-administered drugs during the hospital stay, and in some specific-to-the-patient cases, while still in the hospital, Sundown Syndrome/ ICU psychosis/ICU Syndrome/acute confusion/encephalopathies and cognitive impairment.

Cardioversion - Risks

Best of luck to your father.

good call cardiostar on the sundown syndrome! after i posted i consulted a friend of my brothers who is retired heart surgeon and he advised me of same. my dad after being home 2 days all of a sudden snapped back to himself again. so strange that a hosp stay of 3 weeks could affect brain so much but i can attest it can. thanks for caring enough to respond, i appreciate you!

You're welcome, and thanks for the update.

That's great to hear that he is back to being his sharp-minded self.

Take good care,
