What is the success rate of ablation of atrial tachycardia?

Atrial Tachy (AT) It depends on the frequency/duration of the at. Infrequent episodes - follow or treat with meds - av nodal or antiarrhythmic drugs. Frequent episodes consider ablation if meds fail. Sometimes difficult to induce at ep study and cannot ablate due to need to MAP out the arrhythmia. Success rates in the area of 70-80% if frequent and not multifocal - coming from multiple areas. Ep md.
Great question. It's variable depending on location (left vs right sided). Talk to the electrophysiologist who would perform to get best information specific.

Can anyone tell me something about ectopic atrial tachycardia? I had an ablation for avnrt, but still have breakthrough episodes and doc says this.

Different focus. Assuming your av nodal re-entrant tract was well and fully ablated, and you're now having a different tachycardia, your cardiologist is suggesting that there is an abnormal spot in the atrium initiating rapid abnormal beats. May need different drugs or another procedure. Read more...
Atrial Tachy. Ectopic atrial tachycardia is cause by an abnormal focus in the atrium causing the heart rate to increased. This can certainly be ablated but complexity depends on the location - right vs. Left atrium. Medication may also be tried. Best of luck. Read more...
