Doris, a 78-year-old woman comes to see you, her GP, following a “funny turn” the other day whilst she was out at lunch with friends. She stood up from the dinner table and felt a bit dizzy, she remembers feeling clammy and then blacking out. The next thing she remembers is coming around slumped in her chair. Her friend who witnessed the event told her that she went very pale and collapsed into the chair, she then began to jerk her arms and her legs. The restaurant called for an ambulance. Doris tells you that when the paramedics arrived 15 minutes later, she felt much better and was sitting having a cup of tea. 

On examination she has a normal neurological exam. On listening to her heart, you can hear an ejection systolic murmur. She has a heart rate of 77 and her blood pressure is 118/79.
