What is Arrhythmia? Arrhythmia refers to heart rate or rhythm changes caused by abnormal electrical activity within the cardiac tissue.
These abnormalities may cause:
- Tachycardia: an abnormally fast resting heartbeat of over 100 beats per minute.
- Bradycardia: an abnormally slow resting heartbeat of below 60 beats per minute.
- Irregular heart rhythm, which may include premature or extra heartbeats.
What Are the Types of Arrhythmia?
In addition to being defined by the rate and regularity of the heartbeat, arrhythmias are also defined by the origin of the abnormality.
Supraventricular Arrhythmias originate in the atria or in the conductive pathway connecting the atria to the ventricles and include:
- Focal and multifocal atrial tachycardia
- Atrial fibrillation
- Atrial flutter
- Paroxysmal supraventricular tachycardia
- Atrioventricular nodal reentrant tachycardia
Ventricular Arrhythmias originate at the level of the ventricles and include:
- Ventricular tachycardia
- Ventricular fibrillation
