Primary Outcome Measures :
  1. Cost of diagnostics per patient until final cardiac diagnosis has been made

Secondary Outcome Measures :
  1. Cost of diagnostics until final diagnosis has been made
  2. Rate of correct cardiac diagnoses
  3. Comparison of time needed to make a diagnosis
  4. Comparison of pre-syncopes and syncopes occuring in both groups after enrollment
