3rd lead

Not enough info

I checked your bio and without knowing the number of leads or the model I am unable to determine if your question pertains to a lead replacement (dual chamber to dual chamber) or a third lead for an upgrade from a dual chamber to a CRT (3-lead CRT). If you elaborabe some we can make a better effort to respond.. 

Hi and welcome!

I see that you've loaded info as Dave requested. I assume your Boston Scientific is a dual chamber pacemaker. As stated online:

A dual chamber pacemaker has two leads, one in the right atrium and one in the right ventricle, to monitor and stimulate both chambers of the heart. The leads work together to mimic the natural contraction of the heart's chambers, which helps improve blood flow and relieve symptoms of arrhythmias.

A third lead may be added to a pacemaker in the form of a biventricular pacemaker, also known as a cardiac resynchronization therapy (CRT) device. A biventricular pacemaker has three leads, one in the right atrium and one in each ventricle. This allows the pacemaker to coordinate the contractions of the ventricles so they pump together, which can help with heart failure symptoms.

To add a lead to a dual chamber pacemaker, a cardiologist would typically perform a minimally invasive procedure where they access a vein in the chest, usually under the collarbone, and carefully guide a new lead wire through the vein using fluoroscopy (X-ray imaging) to position it in the desired heart chamber (either the right atrium or right ventricle), then connect it to the existing pacemaker generator, effectively creating a "third lead" for a more comprehensive pacing system; this procedure is usually done under sedation and requires careful placement of the lead to ensure optimal function.

Like any surgical procedure, there are potential risks associated with adding a lead, including bleeding, infection, and lead dislodgement.

Several here have mentioned adding a third lead and hopefully someone will come forth with their personal experience.

I am on my first pacemaker which is over three years old and is already a three lead CRT-P, so I can't advise on how it is to undergo adding a lead. I can say that my CRT-P improved my ejection fraction to normal in time. I wish you well and an easy experience.

3rd Lead

I had a 3rd lead added to my system Monday.  My first pacemaker was dual chamber pacing and lasted ~10.5 years.  My battery life was depleted and it was time for it to be changed, so they did an echo on me and found my EF had dropped, showing signs that I needed a 3rd lead for cardiac resynchronization therapy.  I could tell that either my previous pacemaker was either not working as well due to battery depletion or I could feel the effects of the EF drop.

I had a long talk with my doctor, who is a great fit for me and I trust fully to make the right suggestions for my treatment, and decided that he was right in having this 3rd wire.  I am only 4 days in, and I am sure my EF has not yet improved much but I do feel an improvement between Monday morning and now.  I have had no issues and only sore at the incision site.

I do not know if I have the answers to your specific questions, but I will help in any way I can.
