crt and av node ablation

Crt checked yesterday and top atrial of heart still trying beat 150 to 175 at times and Dr didn't suggest a fix. Anyone she'd some light on this problem.

AV-node ablation

I guess your doctor either didn't properly explain to you what an AV-node ablation does, or you didn't understand him when he explained it.

The AV-node ablation does not stop atrial tachy-arrhythmias. These arrhythmias originate somewhere in your atria, so to stop them, you have to find these spots and ablate them. The AV-node has nothing to do with these arrhythmias, other than that it passes the electrical signal coming from them on to the heart's ventricles. Consequently, an AV-node ablation only prevents that atrial tachy-arrhythmias are conducted by the AV-node in a 1:1 pattern to the ventricles. While your atria are in tachycardia, your ventricles are being paced at a steady and appropriate rate. So, of course, if you had atrial tachycardia before the AV-node ablation, your atria are now still beating too fast at times. But what matters is that your ventricles are not following that fast pace from the atria. At least they should not, but the pacemaker can be programmed to track the atrial rate up to a certain programmed, max. atrial rate. You do not have a problem now, it's what was supposed to happen when you had the AV-node ablation.

Yes they did cover that some but of course where it was causing the worst issue was in the ventricles sending my heart beat from 250 to 300 beats per minute. they say no more ablation to many places to fix and wall of heart not capable of carrying good current. Thanks Inga just trying to get used to new things that have to live with and hoping someone out there knows something to make life better.

Hybrid Maze

Skaggsoak, There's several ways to combat this problem and there's MANY treatments in the medical bag to deal with it. They can do an ablation to correct it (worked for me) or if need be they can enter through the right and left chest walls (through the ribs) and perform what's known as a Hybrid-Maze procedure. This procedure allows the electrophysiologist to access the paramecium (sac that covers the heart) and cuts and moves a section of it aside. Then using a series of instruments from both sides of the chest, they wrap a cauterizing device around your heart and burn 7 lines which permanently BLOCK the additional beats you SA or AV node is producing. It has a 90+% success rate. Here's a video to give you a better idea of what this procedure does. https://www.youtube.com/watch?v=2jdY__dB9e4
