Syncopal episodes come on rapidly and last only for a short time, with a spontaneous complete recovery. Presyncope is the feeling that one is about to lose consciousness, but without any actual TLoC; it should be investigated in the same way as syncope. This toolkit consists of a variety of ‘new and useful bits’ summaries, covering the differential diagnosis, clinical assessment, red flags and considerations to do with work and driving. More information is available in the various courses in

This may lead to treatment with medication such as fludrocortisone and midodrine, or occasionally pacing or ablation procedures - others are mentioned in the individual NUBs. Referral should be particularly considered where syncope occurs frequently, is associated with trauma (see</span>

Commissioning GPs might want to think about whether they have a syncope clinic in their area and if not, how they could commission one, as they tend to lead to faster diagnosis and more cost-effective care.

Risk of overdiagnosis if there are incidental findings on ECG – an arrhythmia which is not accompanied by syncope may not be the cause of syncope which happens at another time. 24-hour ECG is generally unhelpful unless symptoms occur at least once per day.</font>
