Arrhythmia

Bradyarrhythmia

Arrhythmia with normal heart rate

Tachyarrhythmia

The origin of the impulse: Atria

The origin of the impulse: AV junction

The origin of the impulse: Ventricles

Sinus arrhythmia

Accelerated junctional rhythm

Accelerated idioventricular rhythm

The origin of the impulse: Atria

The origin of the impulse: AV junction

The origin of the impulse: Ventricles

Narrow complex tachycardia (SVT)

Wide complex tachycardia

Sinus bradycardia Low atrial focus tachycardia First degree AV block Second degree AV block Complete or third-degree AV block Sick sinus syndrome

Junctional escape rhythm

Isorhythmic A-V dissociation Slow VT (idioventricular rhythm) Ventricular escape

The origin of the impulse: Atria

The origin of the impulse: AV junction

The origin of the impulse: Atria or AV junction

The origin of the impulse: Ventricles

Atrial fibrillation Atrial flutter Ectopic atrial rhythm Multifocal atrial tachycardia (MAT) Paroxysmal atrial tachycardia (PAT) with block Premature atrial contractions (PAC) Sinus tachycardia Wandering atrial pacemaker Sick sinus syndrome

AVNRT AVRT (accessory pathway): - Wolff-Parkinson-White syndrome (WPW) - Lown-Ganong-Levine syndrome (LGL)

Accelerated junctional rhythm

SVTAC (SVT with aberrant conduction): Left bundle branch block Left anterior hemi-block Lefo posterior hemi-block Right bundle branch block Trifascicular block

Ventricular tachycardia Ventricular fibrillation Ventricular parasystole

Accessory pathway Wolff-Parkinson-White syndrome (WPW) Lown-Ganong-Levine syndrome (LGL)

Paced rhythm Pacemaker-mediated tachycardia Runaway pacemaker syndrome Sensor induced tachycardia
