You are currently viewing Cardiac Syncope Mnemonic

Here is a quick mnemonic “SINUS NODES to remember about Cardiac Syncope

This can be valuable for patients as well as medical doctors, nurses & students doing their clinical rounds. You can also find it very useful for med exams like USMLE, NEET PG, FMGE, NExT & NCLEX exams

Cardiac Syncope : How To Remember Easily ?

  • S – Structural disease may lead to syncope by compromising cardiac output.
  • I – Inherited disorders like the long QT syndrome, Brugada syndrome, and catecholaminergic polymorphic ventricular tachycardia can cause syncope and arrhythmias.
  • N – Numerous medications of several classes may also cause bradyarrhythmias of sufficient severity to cause syncope.
  • U – Unstable cardiac electrophysiology due to mutations in ion channel subunit genes can lead to syncope and arrhythmias.
  • S – Syncope can occur due to arrhythmias and structural heart disease.
  • N – Nodal dysfunction, such as severe sinus node dysfunction or sinoatrial block, can cause syncope.
  • O – Orthostatic hypotension may result from aggressive treatment of cardiac failure.
  • D – Disorders like ventricular tachyarrhythmias can frequently cause syncope.
  • E – Electrical abnormalities in the heart, such as AV block and prolonged repolarization, contribute to syncope.
  • S – Stokes-Adams attack refers to syncope caused by bradycardia or asystole.
  • Y – Yes, syncope can be caused by the compromised hemodynamic function during ventricular tachycardia.
  • N – Na+ channel abnormalities, like mutations in the SCN5A gene, are associated with Brugada syndrome.
  • O – Other pathophysiologic mechanisms of syncope may be contributed by structural heart disease.
  • D – Diuretics and vasodilators used in the treatment of cardiac failure can lead to orthostatic hypotension.
  • E – Exercise-induced or stress-induced ventricular arrhythmias may occur in catecholaminergic polymorphic tachycardia.
  • S – Syncope may result from ventricular arrhythmias caused by acquired QT interval prolongation.
