UNEXPLAINED SYNCOPE

Arrhythmic CausesSinus node dysfunctionTachyarrhythmiasAV Block

Cause of syncope undetected in 50% of patients1 year mortality is 6%! (unknown cause)1 year morbidity is 12% (non-cardiovascular)1 year mortality is 20-30% (cardiovascular) (untreated)Mortality & incidence of sudden cardiac death are determined by the presence of underlying heart disease

NATURAL HISTORY OF H.O.C.M

Annual mortality 3% in adults, 6% in childrenSymptoms my be unrelated to the gradient, but my relate to the onset of atrial fibrillationDeath is most often sudden & difficult to predictYoung age of diagnosis (<30)Malignant family historyHypertensive response to exerciseGenetic abnormalities associated with SCDOminous history of syncope (childhood) NSVT

MANAGEMENT OF H.O.C. M.SymptomsDiuretics for pulmonary congestions only

Beta Blockers-mainstay of treatment for angina, dyspnea, presyncope Not known if BB prevents SCD

Verapamil can be tried if BB not toleratedAmiodarone ? improves prognosisSotalol experience is limited

Avoidance of Strenuous ExerciseConversion of Atrial FibrillationDefibrillator ImplantationSeptal AblationMyomectomy & mitral valve repairTransplantation.
