Can you have a catheter ablation for a heart arrhythmia?

Yes: Catheter ablations for cardiac arrhythmias are now well-established procedures. The specifics in terms of likelihood for success and/or complications depends on the exact nature of the dysrhythmia. You should see a heart rhythm specialist called an electro physiologist for more information.

But of Course!: Can and often should. It depends on which arrhythmia though. Some can be treated by almost all electrophysiologists and some require eps with special training or competence. It can be hard to find the best person in a given area for your specific issue.
