Pacemaker and ICD Replacement in Reseda, CA
Implantable pacemakers, ICDs, and CRT devices contain batteries that eventually run low. When that happens, the physician typically replaces the device. The original leads often remain in place. Call the office about device-care questions.
Why the whole device is replaced
The battery and other parts are sealed inside a metal case during manufacturing. The seal prevents anything from entering or leaving the device. An implantable device cannot be opened and resealed, so when battery energy runs low the entire generator is replaced.
In most cases the leads can remain in place. Recovered education described replacement as usually easier and faster than the first implant for that reason.
When replacement is planned
Clinic checks track battery status. Recovered pacemaker-check education stated that many pacemaker batteries last between 5 and 10 years, and that the technician or cardiologist advises when a new generator is needed. Actual longevity varies by device and how it is used.
Do not wait for symptoms to assume a battery is depleted. Keep scheduled follow-up.
Preparation notes from recovered education
Replacement is often done in a hospital or day-surgery setting. Many people go home the same day and should not drive immediately afterward, so plan a ride.
You may be told not to eat or drink, or not to take certain medications, for a number of hours before the procedure. An IV is placed. Medication makes you sleepy but not always fully unconscious. Confirm prep with your physician — flagged for approval.
During the procedure
The skin near the shoulder is numbed. The physician makes an incision near the existing device, which sits just under the skin. Recovered steps included disconnecting the leads, removing the old device, checking that the leads will work with the new device, placing the new device, and reconnecting the leads. The system is checked before the incision is closed.
If a new defibrillator or CRT-D is being tested, you may be asleep for part of the procedure because testing can send a shock to the heart.
After replacement
A short recovery-room stay is typical. Pain medication may be recommended. Recovered education advised asking before using aspirin, which can increase bleeding risk. Call if the incision becomes reddened, swollen, or more painful.
Recovery is often quicker than after the first implant, but instructions still come from your team.
When to contact a physician
Call the Reseda office about battery alerts, replacement scheduling, or wound questions. Seek urgent care for fever, drainage, or opening of the incision as directed by your physician.
