Who Needs Catheter Ablation?

Your doctor may recommend catheter ablation if:

  • You have an arrhythmia that medicine can't control.
  • You can't tolerate the medicine your doctor has prescribed for your arrhythmia.
  • You have certain types of arrhythmia. (Your doctor can tell you whether catheter ablation can help treat your arrhythmia.)
  • You have faulty electrical activity in your heart that raises your risk of ventricular fibrillation (v-fib) and sudden cardiac arrest (SCA). V-fib is a life-threatening arrhythmia. SCA is a condition in which your heart suddenly stops beating.
