PACEMAKER IMPLANT

Description:

Implanting of a double chamber pace maker surgically to help set a slow heart beat is called Pacemake implantation

The most common reason for a pacemaker is a very slow heartbeat or bradycardia. A pacemaker resets the heart rate, ensuring adequate blood and oxygen supply to the brain and other parts of the body.

While implanting a dual chamber pacemaker, wires are placed in two chambers of the heart. One lead paces the atrium and one paces the ventricle. This approach more closely matches the natural pacing of the heart. This type of pacemaker can coordinate function between the atria and ventricles.

A dual-chamber pacemaker is small, electrical device that can be implanted into the chest to regulate the heartbeat. It generate's electric impulses that are sent to the right atrium and right ventricle of the heart, thereby stimulating contractions and allowing the two chambers to maintain correct rhythm.

The decision to implant pacemaker will usually be taken by your cardiologist when medications and less-invasive procedures are not effective in correcting your heart problems. A dual-chamber pacemaker is often suggested for a weak heart which cannot maintain timing of the right atrium and ventricle.

Battery life is at least 10 years. Incase of a low battery a surgeon can implant a new generator(body of pacemaker)and reconnect the wires that are already in place.

A dual-chamber pacemaker surgery can be performed in day under under localised anesthesia. A small incision is made in the upper-left side of the chest and the dual-chamber pacemaker is implanted just underneath the skin. By using 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. The pacemaker is then tested well before the surgical scar is closed.

Post Operative care:

The patient is kept overnight after the procedure for monitoring . Follow up visits are a must in the first six months are important to ensure that the settings of the pacemaker are as desired. Post this period checkups are recommended only once or twice a year.

Post Implantation, patients are not allowed to lift the affected arm over the head on the side, the pacemaker has been implanted for about 2 weeks. If you are given a prescription for an antibiotic, ensure that you take medicine properly.

Risks and Complications

Like with other invasive surgeries, internal bleeding, infection, hemorrhage, and embolism are possible complications. Also common in patients with temporary pacing systems is risk of an infection. Antibiotics given can usually take care of this however in case of a severe infection, the pace maker may have to be removed.

Pacemaker syndrome also develops in approximately 7% of pacemaker patients with implantation of single-chamber pacing systems. The patient suffers from low blood pressure and dizziness that are symptomatic of bradycardia. It can usually be taken care of by implant of a dual-chamber pacing system.

Other complications may include, damage to your blood vessels or nerves near the pacemaker. A few patients may also suffer from a collapsed lung.
