Different Kinds of Tachycardia

• There are different kinds of tachycardia: ventricular tachycardia, supraventricular tachycardia, sinus tachycardia, paroxysmal atrial tachycardia and atrial fibrillation.
  
  

Ventricular Tachycardia

• Another name for ventricular tachycardia is abnormal heart rhythm. It is a common culprit of heart attacks and/or scarring of heart tissue. Patients with this tachycardia must be monitored closely as with all heart patients.
  
  

Superventricular Tachycardia

• Supraventricular tachycardia is when the heart beats fast even without exertion. Signs of supraventricular tachycardia are light-headedness, a pounding pulse and a heart that feels like it's racing. A person might also experience chest pain, sweating, shortness of breath and/or fainting.
  
  

Sinus Tachycardia

• Sinus tachycardia is caused by the heart's electrical system firing too quickly. Indications of paroxysmal atrial tachycardia are light-headedness, chest pressure and shortness of breath.
  
  

Atrial Fibrillation

• Atrial fibrillation is when the atria (the two filling chambers) of the heart do not beat in a pattern but shake uncontrollably. The signs of atrial fibrillation are light-headedness, chest pressure and shortness of breath.
