Silly Question?!

If you have a dual chamber pm, does the lead to the ventricle pass through a valve, and if so, would this stop the valve closing properly?

What effect does this have physically, do you know?
Could this be the reason a lot of people (including me) on this site have palps? Could it be to do with blood leaking back through the valve or is that nonsense?!

Thanx bout the tip re St judes website, I'll do that. My mum always used to say that i asked too many questions, i think i drove her ( and tha nuns at my school) mad, but my mind is always whizzing round with questions about everything. Not the most relaxing way to be!
I have had a atrial septal defect which was diagnosed when i9 was 17 which I believe is a small hole btween the Atria and it hasn't needed any treatment or got worse over the years so i suppose we can live quite happily with these gaps as long as they aren't too big!
I get the impressrion you are a bit of a maverick! Would that be a fair assesment? Whatever you are you are funny!
Have a lovely weekend, Jan

I never knew they could put them thru valves. I have an ICD and I know the lead that detects and treats with shocks was threaded through a vein into my heart. My ventricular lead sits on the outside of my heart to help the pump and assists in pacing when my afib will allow. I'll have to find out more about this.

Ahh heck

Now you are getting to technical for me. All I was told is that it is now sitting on the outside of my heart assisting in the pumping function. Thats good enough for me cause its working! After 2 OHS and a slight stroke,,its all I can absorb at this time. I'm more a learn as I need kind of gal.

get its name as it is attached to the outside of the heart. My heart surgeon did this the same time he replaced my valve. I am still learning what questions to ask the doctors. Its all confusing to as there is so much I have trouble understanding. To me its just awesome what they can do to us.

Hi lb151!

Just curious. Was the valve that was replaced the same valve that the leads (or cables in your case) would have gone thro to the ventricle. If sp would that be why they had to avoid it and attatch to the outside of your heart?

Not necessarily

The latest approach preserves normal, physiological contraction of the ventricles, and since it paces the His bundle on the atrial aspect of the tricuspid valve, it does not go through the valve. In additon, the pappilary muscles that control valve opening and closing contract normally, preventing regurgitation. Google His bundle pacing if you are interested,

Pardon!

Sorry Terry, you lost me there too!
How can the lead go into the ventricle if not through the valve? I don't understand that at all!
Is there any way you can put that that a slightly clueless ( but very interested) old codger can understand!
