The elder George Bush had this condition arise while president and didn’t resign. Shep, you ignorant twit!
According to the doctors’ plan, if the drugs failed to affect the arrhythmia — as initially they did — an electrical shock would be administered the following day, a common way of returning a patient’s rhythm to normal. When it was announced that Dan Quayle would be acting president under the Twenty-fifth Amendment provisions while Bush was under anesthesia for the cardioversion — if it was required — a different kind of shock reverberated across the nation. The prospect of Quayle as president brought home sharply the electorate’s lack of confidence in his ability to lead. [1a]
The drugs were effective. By 10:25 pm on May 5, Bush’s heart rhythm was normal. About 5 am the following morning, however, atrial fibrillation recurred. It was decided (by whom?) to continue the drugs rather than use electrical cardioversion. Bush returned to the White House later that day. [1a]. Comment: It would be useful to have information on how long Bush used these medications. Both digitalis and procainamide can affect higher mental function.
