Syncope Evaluation (ESC 2018): Syncope Episode → Initial Evaluation → Diagnosis Certain? → Treat Accordingly.

Interactive Decision Tree

Mini Map

Algorithm Steps

  1. Start

    Syncope Episode

    Transient loss of consciousness

    1. Action

      Initial Evaluation

      History, exam, ECG, orthostatics

      • Detailed history (patient + witness)
      • Physical examination
      • 12-lead ECG
      • Supine and standing BP
      1. Decision

        Diagnosis Certain?

        Can etiology be determined?

        If Yes:

        1. Outcome

          Treat Accordingly

          Manage identified cause

        If No:

        1. Decision

          Risk Stratification

          Assess for high-risk features

          1. Action

            Low Risk

            Outpatient management

            • No cardiac history
            • Normal ECG
            • Typical reflex features
            • Situational triggers
            1. Outcome

              Reflex Syncope

              Education, hydration, countermeasures

          2. Action

            Uncertain Risk

            Syncope Unit evaluation

            • Neither clearly high nor low risk
            • Expedited outpatient workup
            • Holter/event monitor
            1. Outcome

              Unexplained

              ILR consideration if recurrent

          3. Action

            High Risk

            Admit for evaluation

            • Continuous ECG monitoring
            • Echocardiography
            • Consider EP study
            • Risk assessment scores
            1. Outcome

              Cardiac Syncope

              Treat underlying cause, consider device

          4. Warning

            High Risk Features

            Require admission/urgent workup

            • Structural heart disease
            • Abnormal ECG
            • Syncope during exertion
            • Syncope while supine
            • Family Hx sudden death
            • Severe anemia
