Single and Dual Chamber Pacemakers

What is a permanent pacemaker?

What is an implantable cardioverter defibrillator (ICD)?

The following may shed a little light on the subject for you. What is third-degree or complete heart block? Complete heart block complete AV block means that the heart's electrical signal doesn't pass from the upper to the lower chambers.

When this occurs, an independent pacemaker in the lower chambers takes over. The ventricles can contract and pump blood, but at a slower rate than that of the atrial pacemaker. I hope you can have a heart to heart discussion with your doctor. From what you tell us there seems to be more questions than answers right now. I wish you the best in getting your problem solved. Starting about a month before pm, I noticed that my hear rate wont go up even when I was running, also I got dizziness, and kind of electric shock for about 5 sec.

They said that the upper chamber seems to be fine but the signal cannot reach the lower ones. So my lower chamber needs to be paced. My heart rate was about Sorry I forgot to answer your question, Robshahamat - You want the two leader because the top lead will send a signal to the computer telling it when to zap the bottom half.

If your sinus node the top one is ok, and your av node is bad like me the top lead will tell the bottom one when to pace you. I thought my voltage was only 1. I'm surprised your voltage is so high, or is mine just low? Hey guys, the voltages you are referring to are derived from testing. Each time you go for a check the tech does a test called a threshold test. Depending on the test results the tech up or lowers the outputs to allow for a two to one window or double what you need to allow for subsequent changes.

Some devices also have circuits that do this automatically. They self test and adjust to the self check. One name for this is auto capture. It has nothing to do with how you respond to exercise. It does help to prolong battery life. As your top chamber is fine it dictates what your heart rate should be.

With complete heart block this dictation of the heart rate does not reach the lower chamber. Thus your lower chamber will go slower.

What the pacemaker does is restore the connection between the upper and lower. So when your top chamber says go faster your bottom one will. You say you have a VDD pacemaker. If it really is a VDD pacemaker it means that although it is only one lead the part that passes through the upper chamber the atrium has an electrode. In this way your pacemaker is still getting some of the information from the upper chamber.

If you look at the code VDD the first letter means the chamber it is paces in.. The second letter means where is senses see's electrical activity and this is a D for dual which means is senses in the atrium and the ventricle upper and lower.

Two wire leads run from the generator to the heart. The batteries in modern pacemakers usually last for at least 10 years. When a battery does run low, a surgeon can implant a new generator and reconnect the wires that are already in place.

In most cases, a dual-chamber pacemaker surgery can be performed in about one hour in a specialty clinic or general hospital. Before the procedure, a patient is given an injection of localized anesthetic in the chest to numb the area. A small incision is made in the upper-left side of the chest and the dual-chamber pacemaker is secured just underneath the skin.

With the aid of real-time x-ray imaging, the surgeon guides two wires into the subclavian vein and directs them to their respective chambers in the heart. The wires are connected to the pacemaker and tested before the surgical scar is closed.

After the procedure, most patients need to stay in the hospital for at least a day so doctors can monitor their conditions and make sure their pacemakers are functioning properly.

Frequent follow-up visits in the first six months are important to determine if pacemaker settings need to be adjusted. When patients respond well in the six-month period, they may only need to attend checkups once or twice a year. By making smart lifestyle decisions and attending scheduled doctors' visits, most people who receive pacemakers are able to extend their lives by years or even decades.

One of our editors will review your suggestion and make changes if warranted. Note that depending on the number of suggestions we receive, this can take anywhere from a few hours to a few days.
