Most cardiac causes of nocturnal syncope, including repolarisation abnormalities, can be excluded by a normal ECG.2 Interictal (including sleep) EEG is useful to exclude epilepsy, which is the main differential diagnosis, remembering that this test has a sensitivity of only 0.50.75 in most series.1,5,15 Ideally, we require video monitoring of further episodes in other patients with continuous polysomnographic recordings.
