Arrhythmias - Differential Diagnosis Algorithm



Bradyarrhythmia (<60 bpm)

 • Sinus Bradycardia

 • Sick Sinus Syndrome

 • SA Block

 • AV Block (ISt/2nd /3rd degree)

 • Junctional Escape Rhythm

 • Ventricular Escape Rhythm

Abnormal Beats

 • Premature atrial contraction

 • Premature ventricular contraction

Tachyarrhythmias (>100 bpm)

 - Narrow Complex - Regular Rhythm SVT (constant R-R Interval)

     • Sinus Tachycardia

     • Monofocal Ectopic Atrial Tachycardia

     • Aflutter

     • AVNRT

     • AVRT (ie. WPW)

 - Narrow Complex - Irregular Rhythm SVT (variable R-R interval)

     • AFib

     • AFIutter with Variable AV Conduction

     • Multifocal Atrial Tachycardia

 - Wide Complex - Regular Rhythm (constant R-R Interval)

     • Monomorphic VT

     • Regular rhythm SVT with conduction aberrancy

 - Wide Complex - Irregular Rhythm (variable R-R interval)

     • Polymorphic VT (including Tosades de Pointes if in a setting of long QT)

     • Irregular rhythm SVT with conduction aberrancy
