Head-up tilt testing in a heterogeneous population has a low yield. Simple clinical characteristics define the type of patient who is likely to have a positive tilt test and the patient who is not and in whom other investigations should receive priority. The great majority of positive tests will occur during prolonged baseline testing if this is used. Isoprenaline and edrophonium produced similar additional yields of positive tests.
