my mom drove all the way to the hospital (its an hour drive to the one dad’s at) only to be told that dad is not going home and infact is in the icu once more. he had more of those weird arrythmia attacks which cause his heart to beat weird. when his heart does that the defib goes off and shocks him to try and regain a normal rhythm. so either the medication they gave him didn’t work, or something else is wrong.
