Whether it is conventional, without battery or wireless, it has been making our hearts beat faster for over 60 years. The pacemaker (or pacemaker) improves a heartbeat too weak or irregular, especially in the elderly suffering from cardiovascular illnesses.
Regarding the wireless pacemaker, a series of tests was carried out between February 2014 and June 2015 on more than 500 patients for the Nanostim model, developed by the American company Saint Jude Medical. The results of these analyzes, made public at the end of August in the New England Journal of Medicine, are very encouraging: the wireless pacemaker was found to be effective in over 93% of cases and only 6% of patients developed complications within six months of the procedure.
Less risk of infection and wear
This type of pacemaker has been in use since 2013. Measuring only four centimeters, it is directly implanted in the heart during a 30-minute surgery. Its main advantage lies in the absence of a wire which usually connects the pacemaker housing implanted under the skin and the lead directly attached to the heart. This thread is indeed the source of infections and risks associated with its wear, which causes complications requiring surgical interventions. Another advantage of the Nanostim: the lifespan of its battery, which is estimated at 15 years. The longevity of the batteries currently in use ranges from 7 to 15 years. When the battery stops working, an operation is necessary to replace the case in the case of conventional pacemakers. For Nanostim, it would only be a matter of implanting a second pacemaker in the heart, without removing the first.
