What is a common complication to monitor after pacemaker implantation?

• A. Bleeding at the implantation site
• B. Infection at the site
• C. Nausea
• D. Seizures

Answer: (A)

Bleeding into the pocket where the pacemaker generator sits is the most common complication to watch for after implantation. Creating that pocket and threading leads through a vein can injure small vessels, and many patients are on anticoagulants or antiplatelet therapy, all of which raise the risk of post-procedure bleeding. A developing hematoma shows up as new swelling, tenderness, bruising, or a firm, enlarging lump at the site and can cause wound problems or even infection if not recognized promptly. The usual focus right after the procedure is on achieving good hemostasis during the operation and then monitoring the incision, keeping an eye on the size of any swelling, and watching for changes in vital signs or blood counts. Infection is important but occurs less frequently than a hematoma, and nausea or seizures are not typical direct post‑implant complications.
