Exploding head syndrome: new observations

Background and purpose The etiology of 'exploding head syndrome' (EHS) is currently highly controversial and its management is unknown. The object was to explore these. Methods This observational study describes my personal experience of EHS and discusses its implications. Results I experienced, while suffering from EHS, recurrent episodes of transient cardiac arrests due to sick sinus syndrome. Implantation of a cardiac pacemaker resulted in immediate, dramatic, permanent cessation of both cardiac arrest episodes and EHS. This has not been reported previously. Conclusions This striking temporal relationship indicates a possible association between EHS and sick sinus syndrome.
