Dear Cardio Dr.
I have been experiencing inappropriate sinus tachycardia for 17 years and although I am mildly asthmatic I was treated with beta blockers and until now this has successfully controlled the tachycardia. However in the last 18 months I have been plagued by asthma symptoms and the tachycardia has aslo got worse - it breaks through the beta blockade. As a result of this |I have been hospitalized a few times for the arrhythmia.
I had an electrophysiology study carried out and the doctors could not find an extra pathway and I was diagnosed with IST in February 1999. I then underwent a sinus node modification at the Royal Brompton Hospital , London which failed to solve the problem. I have been offered the chance of another ablation but if this fails I am told that my AV node must be destroyed and a permanent pacemaker implanted. I would be grateful if you could advise me on the following: Would I be pacemaker dependent following AV Nodal ablation and if so, what would happen if the pacemaker malfunctioned. Are pacemakers very reliable these days? I'm sorry this message is a bit long, but I,m really worried about the procedure. I have no choice but to go ahead as I've tried all the meds and my doc says this may be the price I'll have to pay to get rid of my symptoms. Thanks a lot for your time.

If your AV node is ablated, you would be almost 100% dependent on the pacemaker. However, there are many people in this situation. Pacemakers today are very safe. When they fail, it is almost never suddenly, but gradually over months, allowing time for doctors to take corrective measures. Pacemaker technology has greatly improved over the last few years and continues to evolve.
I hope this has been useful. I wish you the best of luck. Feel free to write back.
