Pacemaker surgeries are generally safe, and most complications are temporary, according to Healthline. Life-threatening risks are rare. An infection may occur where the pacemaker was implanted. The patient may have an allergic reaction to the dye or anesthesia used during the operation.
Patients who are taking blood thinners may experience swelling, bleeding or bruising at the generator site. They may also have a bad reaction to the medicine used during the procedure, according to the National Heart, Lung and Blood Institute. There may be damage to nerves and blood vessels near the pacemaker as well.
In rare circumstances, the patient's lungs may collapse. The operation may also puncture the heart muscles and this can cause bleeding into the pericardium of the heart and may require emergency medical attention.
A major concern after surgery is that the pacemaker may lose its ability to control the heartbeat because of a malfunction or if the wire moves out of the correct position, reports the U.K. National Health Service.Learn more about Cardiac Health
