Cardiac arrhythmia occurs when the Heart it does not beat in a regular rhythm. This condition can manifest itself in a heartbeat that is too fast (tachycardia), too slow (bradycardia), or irregular. Arrhythmias can be caused by a number of factors, including:

  • Structural problems of the heart.
  • Electrolyte disturbances.
  • Hypertension.
  • Damage to heart tissue following a heart attack.

  • Heart disease: such as high blood pressure, heart failure or heart valve disease.
  • Conduction system dysfunction: Problems in the heart’s electrical system that regulates its rhythm.

Heart arrhythmia treatments

Treatment of arrhythmia depends on the underlying cause and the severity of the symptoms. Some of the common treatments include:

  • Antiarrhythmic drugs: may be prescribed to control the heart rhythm.
  • Electrical cardioversion: A procedure in which an electric shock is applied to the heart to restore normal rhythm.
  • Catheter ablation: A procedure in which the abnormal heart tissue causing the arrhythmia is destroyed.
  • Pacemaker: A surgically implanted device that regulates heart rhythm.

The choice of treatment will depend on the doctor’s assessment and on the specific conditions of the patient.


Heart arrhythmia is a common condition that affects many people around the world. While it can be concerning, most cases of arrhythmia are not dangerous and can be managed effectively.
