Cardiac considerations
- An echocardiogram and electrocardiogram should be performed prior to general anaesthesia. They should also be performed before undergoing conscious sedation or regional anaesthesia if the last investigation was more than one year previously, or if there had been an abnormal echocardiogram in the preceding 7-12 months.
- For local anaesthesia, an echocardiogram should be performed if there had been an abnormal result obtained previously.
