Key result
Specific history-taking features, including family history of syncope or sudden cardiac death, palpitations, and syncope while supine or during exercise/stress, indicate higher risk for LQTS.
Why the study?
Does history-taking help identify patients likely to have Long QT syndrome among those presenting with syncope?
Case-Control (n=214)
Does history-taking help identify patients likely to have Long QT syndrome among those presenting with syncope?
Specific historical features, including family history of sudden cardiac death, palpitations, and syncope during exercise, emotional stress, or while supine, can help identify patients at higher risk for Long QT syndrome among those presenting with syncope.

May aid LQTS risk stratification in syncope; leaves open need for prospective validation.
Colman et al. (2009) conducted a case-control in Syncope and Long QT syndrome (n=214). History-taking (clinical characteristics and triggers) vs. Non-LQTS syncope patients (ED and vasovagal) was evaluated on Clinical characteristics and triggers associated with LQTS. Specific history-taking features, including family history of syncope or sudden cardiac death, palpitations, and syncope while supine or during exercise/stress, indicate higher risk for LQTS.
