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

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

Estimated Enrollment: 100
Study Start Date: April 2002
Study Completion Date: September 2006
Primary Completion Date: September 2005 (Final data collection date for primary outcome measure)

Ages Eligible for Study:   18 Years to 85 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Two or more episodes of syncope (most likely due to cardiac arrhythmia) of uncertain etiology within the last 12 months or more than one syncope and two presyncopes

Exclusion Criteria:

  • Indication for the implantation of a pacemaker
  • Indication for the implantation of an implantable cardioverter defibrillator
  • Cardiac diseases which need intervention (KHK, aortic stenosis, mitral stenosis, left ventricular [LV] outflow stenosis, decompensated heart failure)
  • Contraindication for a diagnostic procedure requested by the study protocol
  • Enrollment in another study
  • Circumstances or comorbidities which do not allow enrollment
