Red Flags of Syncope

Cardiac syncope may lead to a high mortality rate of approximately 10% at 1 year and is, therefore, vital to identify potentially life-threatening cardiac causes1.

Below are considered reds flags for urgent referral to a Cardiologist:

  • Persistent bradycardia- heart rates < 60 bpm
  • Abnormal structural heart conditions, (presence of a cardiac murmur)
  • Decreased left ventricular ejection fractions < 35%
  • Long QT syndrome
  • Brugada syndrome
  • Ventricular pre-excitation conditions (such as Wolf-Parkinson-White syndrome)
  • Pathological q waves
  • Sustained atrial arrhythmias
  • Ventricular arrhythmias
  • Syncope whilst exercising
  • Syncope whilst supine
  • Sudden cardiac death in family < 40 years old
    > 65 years old, with syncope in absence of prodrome2.
