Heart Ablation

When you have cardiac arrhythmia or dysrhythmia, this means you have an abnormal heart rhythm. Catheter heart is one way to treat this type of heart condition. A cardiologist inserts a thin flexible tube called a catheter into the patient’s heart. Then a special machine will deliver energy via the catheter to the areas of the heart muscles causing the irregular or abnormal rhythm. Essentially, the energy will disconnect the abnormal rhythm’s pathways.


There are instances when catheter heart ablation is used in order to cut off the electrical pathway connecting the ventricles (lower chambers) and the atria (upper chambers) of the heart. The type of catheter heart ablation a cardiologist would perform greatly depends on the kind of arrhythmia the patient has.


Catheter heart ablation is used to treat AVNRT or AV Nodal Reentrant Tachycardia, Accessory Pathway, Atrial fibrillation and atrial flutter, and Ventricular tachycardia.


Your doctor will determine whether a catheter heart ablation is the best treatment for your condition. A thorough evaluation is needed. This includes the following:


  • Thorough review of medical history
  • Complete physical examination
  • Echocardiogram (Echo)
  • Electrocardiogram (ECG)
  • Holster monitor test
  • Other tests including laboratory tests as needed


Once the evaluation is completed, your doctor will meet with you to discuss the possible treatment options. Together, the two of you will then determine if you are a suitable candidate for the catheter heart ablation procedure.


In general catheter heart ablation is considered a very safe procedure. But, as with other invasive procedures, it is not without its risks. The doctors performing this type of procedure will take all the necessary special precautions in order to lessen the risks. The success rate for a catheter heart ablation depends on many variables. Your doctor is the best person to ask regarding this.
