Ventricular Arrhythmias

Ventricular Arrhythmias, are classified as abnormal heartbeats that originate in the lower chambers of the heart and cause the ventricles to beat rapidly.

About Ventricular Arrhythmias

These potential life-threatening arrhythmias do not originate within the Atria (via the sino-atrial node), it originates in the Ventricle and may result in patients presenting with little to no cardiac output, requiring Cardiopulmonary resuscitation (CPR). 


Symptoms may be:

  • Palpitations,
  • Hypotension (low blood pressure),
  • Syncope and dizziness,
  • Shortness of breath,
  • Chest pain, or
  • Unconsciousness.


These Arrhythmias include:

  • Ventricular Tachycardia (VT) and
  • Ventricular Fibrillation (VF) may also be referred to as Sudden Cardiac Arrest (SCA).


There are also many inherited or structural heart conditions that may facilitate the development of Ventricular Arrhythmias such as VT. These may include:

  • Cardiomyopathies (any cause),
  • Hypertrophic Cardiomyopathy,
  • Long QT Syndrome, and
  • Brugada Syndrome.


In many cases, these inherited conditions may be treated with medications to prevent the development of the Ventricular Arrhythmias. Similarly, these patients may be candidates for Implantable Cardioverter Defibrillators (ICD’s) or Cardiac Resynchronisation Therapy in the case that the patients’ have heart failure due to Cardiomyopathy (of any cause).1
