Arrhythmia

What is Arrhythmia?

Arrhythmia refers to the irregular beating of the heart which may feel like your heart skipped a beat, added a beat or is fluttering. A normal heart beats about 60 to 100 times per minute depending on the activity levels of the individual. However, due to problems with the cardiac conduction system, the rhythm of the heart becomes abnormal.

Arrhythmias can be harmless or may cause an emergency. In case you are frequently experiencing abnormal heart rhythms, get in touch with us to consult with our Best Arrhythmia Specialist in Kolkata. 

The types of arrhythmias are divided based on the area of origin and the rate at which the heart beats. If the arrhythmia begins in the ventricles or lower chambers of the heart, they’re known as ventricular arrhythmia. If the condition arises in the atria or upper chambers, they’re called supraventricular. 

In addition, the doctors also classify the arrhythmia types based on the speed of the heart rate. In bradycardia, the heart rate is fewer than 60 beats per minute whereas, in Tachycardia, the heart beats at 100 beats per minute. 

Supraventricular arrhythmias types are as follows -

  • Premature atrial contractions 
  • Atrial fibrillation (AFib)
  • Atrial flutter
  • Paroxysmal supraventricular tachycardia (PSVT)
  • Accessory pathway tachycardias
  • AV nodal reentrant tachycardia (AVNRT)

Ventricular arrhythmias types include the following - 

  • Premature ventricular contractions (PVCs)
  • Ventricular tachycardia (V-tach)
  • Ventricular fibrillation (V-fib)
  • Long QT syndrome
