Anatomical Differential Diagnosis for Arrhythmias
 • SA node: Sinus bradycardia, Sick Sinus Syndrome (SSS)
 • AV node: Junctional escape rhythm, Conduction blocks (1°, 3° and Type 1 2°)
 • His-purkinje system: Conduction blocks (1°, 3°, and Type II 2°)
 • Ventricles: Ventricular Escape Rhythm (i.e. idioventricular rhythm)
Tachy-arrhythmias (ventricular rate > 100 bpm)
 • SA node: Sinus tachycardia
 • Atria: Premature Atrial Contractions (PACs), Atrial Flutter (AFL), Atrial Fibrillation (AF), Paroxysmal supraventricular tachycardias (PST), Focal Atrial Tachycardia (FAT), Multifocal Atrial Tachycardia (MAT)
 • AV node: AV re-entrant tachycardia (AVRT), AV nodal re-entrant tachycardia (AVNRT)
 • Ventricles: Premature Ventricular Contractions (PVC), Ventricular tachycardia (V-tach, VT), Monomorphic VT, Polymorphic VT (i.e. Torsades de Pointes), Ventricular Fibrillation (V-Fib, VF)
