How should I prepare for surgery?

Before your ICD implant, ask that doctor of yours what medications you're allowed to take. It might be necessary to stop some of them before the procedure. For example, it's common for people with diabetes to adjust their medications.   Don't eat or drink anything after midnight on the evening before the procedure. Use this time to make plans for a glorious feast upon recovery.   When you come to the hospital, wear comfortable clothes, though they will put you in a hospital gown anyway.
