On the basis of the main site where abnormal rhythm is generated, we can classify arrhythmias as:Īny abnormal rhythms or Cardiac Arrhythmias which come from SA Node called Sinus arrhythmia. When the heart rate is between 20 – 40 bpm c. When the heart rate is between 40 – 60 bpm If the heart rate is less than 60 bpm we call such type of Cardiac Arrhythmias as Bradyarrhythmias, which are further classified as: When the heart rate is more than > 350 bpm Bradyarrhythmias- Bradycardia: When the heart rate is between 250 – 350 bpmĭ.Fibrillation (Atrial or Ventricular Fibrillation): When the heart rate is between 150 – 250 bpmĬ. When the heart rate is between 100 – 150 bpmī. When the heart rate is more than 100 bpm we call such type of Cardiac Arrhythmias as Tachyarrhythmias, which are further classified as: Bradyarrhythmia- Bradycardia Tachyarrhythmias – Tachycardia On the basis of heart rate arrhythmia can be classified asĢ. Normal cardiac rhythm has the following criteria:Įvery heartbeat should be originated from the SA Node.Īll cardiac impulses should be passed through a normal conduction pathwayĬardiac impulse should be passed through a normal pathway with normal velocity When the heart deviates from the normal rhythm is called arrhythmia so irregular rhythms of heartbeats are known as Cardiac Arrhythmias.
