Were these inapropiate shocks or did you need them ? If I hit my cut off rate the ICD fires mine being 180. You may be having a ventricular response to the A-Flutter, Like supraventricular tachycardia. My device will pick up SVT and V-tach or V-fib only. you may need to have some adjustments in your settings or maybe give the beta-blockers time to take effect. It sure isn`t fun being shocked hope your doctors can figure it out.
You are the first person I have seen who has had an ICD longer than me, my first implant was in 1991. BEST OF LUCK TO YOU.
I've read and have been told that ablation can take months to settle out, other arrhythmias that were never seen before may spring up spontaneously.
ARVD is a tough bugger to offer long term prognosis. Though I've not heard of it advancing into the atriums.
Wow i was pretty impressed reading your post.....1981 you had an ICD implanted? Wow that is totally amazing to me me and obviously they had the medical forsight to know that it would still cont. to do its job 30 years later w. minor adjustments along the road. As far as an ablation for atrial fib/flutters, etc. trust me from someone who knows that ablation will be a heck of alot easier on you than being converted or even the trip in the ambulance. I would do my homework and read up on as much as you can about the procedure but to me it is a no brainer because from my understanding the orginal concept came up for the ablation with the atrial fib/flutter in mind by Drs. Natale and Scheinmann and i believe that is why it is so successful. Itdood is def. right tho it can take up to 6 months for your heart to revert physically and electrically to the procedure and generally speaking my heart doc told me if its going to fail in 80 % of the cases it will fail within a short time of the procedure and generally within 90 days. Good luck....
Thanks for the comments.
Apparently I was a bit unclear. My first V-tach was in 1980, I was studied, but no ablation or implants in 1986. It was 1997 when I got the first ICD (now on the 4th) and when the first ablation was attempted.
At least 9 of the 10 shocks had no V-tach component, the Medtronic tech and the doctors can only say that one of the 10 might have had some ventricular component. but the peaks were all narrow, not the wide form typical of V-tach. (With only one lead, it is impossible to be certain, but some of the shocks came while I was on a 3 lead EKG in the ambulance or the ER, and for those it was clear the shocks were not appropriate.). Some of the time while I was in A-flutter, my vetricle contracted on every atrial contraction instead of the more usual every other, so I was closer to 280 BPM that 140-150 BPM which is, I think, more typical of A-flutter. However, I remained conscious and able to enjoy every second of it.
Hey Dennis....i didn't realize that you had a Medtronic Vascular ICD and now you say its your fourth. You may want to check and be sure that the current one or the past ones that were removed are not on the Medtronic "watch" list for the recalls....i do know that part of the suit that was filed against Medtronic was due to alot of what you are explaining...for giving un-necessary shocks because of the leads in them. I don't mean to be the bearer of bad news with this but we have to all watch out for one another on this site.......sounds a little suspicious to me.....good luck.....
The first ICD I had was recalled due to a bad batch of capacitors. Medtronic provided the replacement for free and paid my part of the installation cost.
The first lead I had was one of the older thick ones, not the thin ones which came later and that others had fail.
The second ICD lasted 8 years before the battery was exhausted.
The 3rd was in only for a couple months since its insertion along with a new lead resulted in an infection, that was treated with Cipro to hold the infection at bay until it was a more convenient time for me to have the removal done.
The 4th ICD and a new lead(the 3rd) were installed on the right side after the 3rd ICD and both sets of leads on the left were removed. It has worked properly, but of course was not capable of discerning the high superventricular tachycardia from ventricular tachycardia reliably at over 170 BPM and cannot treat A-fib or A-flutter.
