Overview

Cardiac arrhythmia is any of a large and heterogeneous group of conditions in which there is abnormal electrical activity in the heart. The heart beat may be too fast or too slow, and may be regular or irregular. A heart beat that is too fast is called tachycardia and a heart beat that is too slow is called bradycardia. Although many arrhythmias are not life-threatening, some can cause cardiac arrest.

Classification of Cardiac Arrhythmia

G01= Accessory pathway

Wolff-Parkinson-White syndrome (WPW)
Lown-Ganong-Levine syndrome (LGL)| G02= Paced rhythm

Pacemaker-mediated tachycardia
Runaway pacemaker syndrome
Sensor induced tachycardia}

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

Respiratory sinus arrhythmia Sinus bradycardia Low atrial focus bradycardia 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 rhythm

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

The origin of the impulse: Atria, AV junction or ventricles Presence of an accessory pathway

The origin of the impulse: Pacemaker
